View Full Version : get loud for cheap / ghetto blaster burb

05-27-2014, 08:59 PM
since forever ive always wanted a "big" car stereo viechle.
a bit ago i purchaced 4 si ht 18s d2 from fourm member 2000lade
and then realized i diddnt have a viechle big enough to stuff 4 in
so i searched craigslist for a while till i got a great price on this old 1990 suburban

time to get loud or fail about 50/50 shot at either way / half full or empty your pick

started off with some front stage - built this center consol front box - ported but having left and right chambers.

for some reason i thought it might be important to have the ash tray still function
so i designed it to be low profile enough to allow that. to do so i fiberglassed to the shape of the floor hump for the bottom. came out pretty cool and gave me a false sence of being capable of doing fiberglass type work.

wraped it in blue fabric donated from my work - almost matches my interior colors
mids were just sitting around in my spare room from forever ago - parts express had a sale on the pearless 6.5 4 ohm for something silly like 14$ each a bunch of years ago - i still had 4 left from then

so now we needed door speakers. this body style burb has nothing in the doors - but the window motors and regulators are 100% in the way of doing any recess mounting of anything in the doors. so anything on this door will have to be all external pod.

glassing - needed to install fleece and mount on the door - glass it wet and shut the door with plastic there so the fleece took the shape of the stupid floor hump where the front seats mount. had i of not done this way - the shape would of had to been worse by alot.

i also just happen to have 2 pairs of crappy 4 way co ax laying in a box doing nothing so i tossed those in the doors

decided to try sanding and bondo on the driver side door pod

sanding fiberglass is the worst. got super frustrated - screwed it down to the table i had and used a belt sander on it.
did some bondo - more sanding - hating it - more bondo - more sanding. got fed up with doing that and just primed it
ill make it look pretty later - i got other crap to build in this thing

http://i214.photobucket.com/albums/cc279/brian84corvette/039_zpsf34dbfd4.jpg (http://s214.photobucket.com/user/brian84corvette/media/039_zpsf34dbfd4.jpg.html)

driver side is half way finished bondo - and primed. pasanger side is still raw fiberglass blue fleece lol. whatever it plays.
used a hole saw on each 6.5 opening and cut the door open as well so the inside of the pods can vent to the inside of the doors.
doors have rattles - added pollyfill to the inside of the pods and it helped the sound of the speakers a bit - but those co ax are pretty not amazing so ... yeah

05-27-2014, 09:25 PM
about this time i took a totaly junk box and stuffed my old re sx 18 d2 in it and tossed it in the back just to see what this burb sounds like with some bass.
one 18 does nothing for loud inside this burb.
how about 2 ?
re sx 18 d2 old style ( exposed tinsel leads and felt pads on the cone for slap ) one was in my old 84 vette like 7 years ago - one brand new factory sealed
decided to build seperate boxes for them as to not experience push pull from the loose sub to the stiff sub.

7.25 cubes net ported at 33hz - i designed the box - i failed at it. more on that later

Very nice job on the pods for someone who has little glass experience

05-27-2014, 09:32 PM
we need some batterys. i bought 3 of this brand new localy. got an ok price but i might of been able to do a little better for the $
http://i214.photobucket.com/albums/cc279/brian84corvette/039_zps2fb45bca.jpg (http://s214.photobucket.com/user/brian84corvette/media/039_zps2fb45bca.jpg.html)

ordered some 1/0 royal exelence from ebay $110 for 25ft red and 25ft black
got a bunch of aluminum dual distro terminals from home depo.
built a battery box right behind my rear seats.

did run of positive and negative from front battery to rear battery bank. big 3 and was about 6 ft short of red and black to finish the batterys up - used copper for now

have stock alternator for now - but i will soon ( less than 2 weeks from now ) i will have a singer 320 hairpin ( 200/220 amps at engine idle = win )

my wiring is hell. everything is just tossed in there - exept i did run the 1/0 nicely under the carpet

05-27-2014, 09:46 PM
then magic happened. my job = event setup and removal - we rent from another similar shop who does alot of audio. im friends with the owner and was telling him about my burb he saw my exitment and gave me a pair of his old 12" peavey black widow electric guitar speakers the dust caps were hammered - so i cut those off and glued on replacments = fantastic free mids !!
so where should i put them ?
doors ? no that would be terribly amout of work to re locate everything... also dont want them in the rear fill area.....
i kno ill take out the existing factory center consol and build a box there for them.
cool - go

this is how it first came out. looks terrible - played ok - filled with pollyfill - sounded amazing. still looks awfull
special note - left and right tweets on the a pillars are infinity refrence

so it plays great. realley warm and alive sounding guitars like red hot chilli peppers / november rain from guns n roses are just astounding up front
but that dang box is so ugly im going to throw up on it.
something has to be done about it.

alright - one million pounds of saw dust later this is what i came up with.

did recess mount on the 12s and cut the front of the box off and used a piece of 12" sono tube to do round over front.
it was awfull doing recess mount on the 12s on a already built and glued together box... and i used my circular saw as a router to fit the sono tube front
it would of probably been easier to just start over from scratch on that box.

box still plays fantastic - filled with pollyfill - both woofs are together for 4 ohm load bridged on 2ch of a old punch 400a4 = 100ish watts per
looks a little better like this now. im sort of satisfied for the time being

05-27-2014, 10:14 PM
so the subs are in and playing now - 40hz and up goes pretty hard. below 38hz the cones move and air goes in and out of the port but its not loud.

here is the link to my box math. i built exactly to that spec.

turns out i picked the wrong location on that drawing to mount my subs. had i of picked mounting point a i would of been good. i chose mounting location c
and the subs were un loading at 38hz down.

today i decided to build a "loading baffle" ( red in the picture ) to help direct the internal air space better and keep the subs from un loading at the lows

and they are both back in now. port issue fixed. my lows have sound now - and my roof flexes like crazy at 25hz tone / 35hz tone is strong and rumbly :)

05-27-2014, 10:29 PM
next up on the list : sound deaden my roof / and doors especialy the front doors.
get some sound processing going on. im using a cadence qxr7 and its terrible. maby get active capable 4 chans. my old school punch 200a4 and 400a4 leave alot to be desired in the tuning of the hz on them....
maby i should buy a headunit instead of just using my ipod to power this entire system lol maby not tho.. i hate headunits haha

o and i have four 18s sitting in boxes wating for me to stop being a little girl and build a wall or a 4th order for them and get LOUD
since im terrible at designing = I NEED HELP designing a ported wall or 4th for theese subs.
at first i thought 4th was out of the question due to c pillar back only for me ( i need to use my back seats i have a kid ) but another fourm member said this :
- You don't need a huge sealed side to get optimal resonance with the SI HT18. Fsc at 2.5 ft^3 (per driver) is 45hz, and drops to 40hz with just a little over 3 ft^3. A 40hz centered 4th with a moderate ratio should get stupid low and move a LOT of air - so maby i can stuff a 4th back there in 3:1 ratio ?

Very nice job on the pods for someone who has little glass experience

thank you for the kind words sir - fiberglassing makes my temper go up in a bad way - but its worth it as the end result is desirable.
the work to get there can be taxing for shure. those pods magicly came out good - but i had a few throw aways as well when the glass warped or shrank ext...
to the pro's at fiberglassing i have a whole new respect for you dudes. its totaly a skill to be good at glass. im not there yet. lol

05-27-2014, 11:56 PM
nice work on everything so far and i like the truck. Also nice fix on the loading wall in those boxes, its cool to see that it worked

05-29-2014, 09:53 PM



so my first attempt at taking a video - aparently i held i phone the wrong way - and yeah not so steady hand.
guess ill try and get better videos later.

also did some measuring in the back. i can build a box inside the truck utalizing the most area avalable - double thick 3/4 on all sides including front and rear the open chamber inside the cabbin would be about 55 to 60 cubes to work with.
is that enough to design a 4th order for my 4 si ht 18 ? they would only want about 14 to 16 cubes on the sealed side + whatever the baffle and bracing will displace
the port opening for the front can ride half in and half out of the enclosure so that wont take away tons of room either

05-30-2014, 12:10 AM
I lol'd at the "re occuring theme.". Haha

06-02-2014, 01:06 AM
i got sick of looking at the center consol arm rest box being raw wood and sono tube - so i laid down a coat of fiberglass inside and out on the top and sono tube area to just make shure its strong - belt sanded it forever - cleaned up with some bondo on the screw holes and smoothed er all out... belt sanded a bunch more. primered it and used some vynal sticker i had left over from a job where i created a gigantic moroccan zebra print arch way. strange client / strange party
but i had it laying in our shop as trash scraps
so free is for me.
started with this:

cut it up in to smaller stripes and applied to the box

going back together with polly fill

i think i over stuffed with polly fill the first time. only used 3/4 of that this time.

decided to start sound deadning process. pulled the rear half of the headliner - and tossed all the junk for the rear ac since it was not hooked up anyway.
packed all the roof ribs with whatever left over tubes of caulking i had laying around my shop. idea was to bond the roof to them slightly and also prevent any metal to metal contact / rub / noise there. - some of the gaps were quite large - so im wating 72 hours before playing bass just to give caulking time to set up good.

im super messy with caulking. always have to mush it with a finger to "help" lol
and since i had a home depo gift card - i picked up 4 rolls of this peal and seal type deadner $16 a roll and still have $4 left on my gift card - thanks santa !

went double thick on all areas of the roof. overlaped the seams. used a longboard skateboard wheels mounted to the trucks to "roll" all of it on for a nice job.
was tough on the arms and neck...
hopefully it will help some. still have to wait a bit to play bass and see if there is any improvment - might do my rear doors next - or might pull the side pannels back there and do that area next. still have a few ft of the cheap o peal and seal leftover - but i might wait and test with what ive done already
if i find that it infact did not help much at all - i might have to pony up and buy some real sound deadner

Interested to see if the peel and seel does anything for you.. a ton of controversy on this forum as to whether or not it works. General consensus seems to be that it doesn't.

But since you clearly have it installed, you should be able to shed some light on that soon.

Great job so far.Def tuned in!

06-05-2014, 04:13 AM
im hoping double thick will do something. at double thick its still cheap - but if i have to go tripple thick it starts getting in to the "real sound deadner" price range per foot used at x amout of layers thick bla bla ...

tomorow on the way to work and home i shall play some and see if she rattles up there on the roof as bad as it did before.

I had horrible results with the peel and seal. I did multiple layers, it just really didnt work very well for me compared to good CLD tiles. but the worst part is it falls off in heat and its just a mess really. Hope it works better for you, this is a cool build man

06-05-2014, 05:40 PM
today was the worst day of this build.

got in my burb today at 10am to drive to work ( south FL its smokin hot already by 10am ) and my truck was an oven
literly i felt heat coming from the back so hot it seemed like something was on fire.
checked the back out.
3 strips of 6" wide had already fallen down = landed on top of my box and subwoofers.
and that was only 10 am.
pic to follow. fml dont use peal and seal on your roof - the hot sun will literly melt it off. it will fall down - and make a big *** mess. you will be angry

figured id try and stick it all back together as best i could. used this aluminum straping tape for ac ducts on all the seams to make all the seperate pieces "one big piece" so hopefully it wont fall down again. maby it will. who knows. i hate that this happened. but thats what i get. fail - learn from it - fix it - do better next time.

so even if it does stay up this time.
its still hot. the hot sun beats down on my roof - transfers to the asphalt of peal and seal - gets that hot - the aluminum face acts like a grill or oven convexing hot in to my truck. literly it was so hot to touch i had to wear a leather glove to press it all back on. id imagine the aluminum surface of that crap was well over 100 degrees on the underside of my roof inside the cabin of the truck. so yeah. even if it stays up and i keep it there - now my truck will be a gigantic slow cooker set to 125deg. from 9am to 7pm every day this summer. im not happy
stay away from peal and seal.
you will be so angry at your self - learn from my fail please

06-05-2014, 07:03 PM
Seriously man I would just cut your losses and throw that crap away. If it's not even sticking to the roof it's not going to have ANY sound deadening properties...

As a side note, I love the zebra stripe center console, haha.

06-05-2014, 07:16 PM
Any of the old timers remember what dynamat was in the 90's? Pretty much what OP used but without the aluminum layer. Personally I've had better luck with home depot products sticking and staying than with some pretty high priced name brand SPL tiles.

Florida and asphault based deadener really don't mix though. That place is terribly hot. Up here I had a fire going in the wood stove yesterday. That jungle heat is for the birds.

06-05-2014, 07:35 PM
im thinking more and more about tearing it all off - and doing a plywood roof of sorts. each suport rib has about 18" between it - i could do 1/2" plywood in between each beam at 48" wide across and use some great expanding foam to spray up in there to keep the roof "stuck" to the ply so it does not flex and make noise.
i gota do something perminent back there to keep everything "solid" cause once i build the wall / or 4th order box it aint coming out.
***** tho.
guess its good that i diddnt spend $65 cash out of my pocket to buy peal and seal from home depo - and had a gift card to "learn" from this experience.
asphalt based deadner and south FL do not mix gota figure out something for my doors now. no way do i want to buy any kind of asphalt type deadner.

06-06-2014, 01:03 AM
You can use Spectrum from Second Skin Audio. It worked great on my car and it was fairly cheap too. You can spray it on with a spray gun. The only thing is you gotta wait like a day for it to dry so it can harden. It will add alot of weight to your roof without a lot of product.

06-06-2014, 07:32 AM
I've never had any problems with second skin deadener falling off...

SDS CLD tiles are also an option if you can get an order placed (they have problems responding to emails)

06-06-2014, 10:29 PM
nothing fell off or saged down even a little bit today. was just as hot and sunny as yesterday.
so i guess ill let it stay like that for a week and see if any more comes down....

had a guy come by the shop today to do returns - i tossed him in the pasanger seat and went for a demo drive.
he had never been in a viechle with this much stereo system and was pretty blown away. by the end of the drive he was pluging his ears with his fingers.
played wiz kalifa on my level / lil john turn down for what / and somethng else i cant remember. but it did give me the slightest bit of un comftorble in my ears today also... first time in the build its been louder than lovely feeling. so maby the roof is helping divert some cone movment energy up front instead of being hopelessly lost in roof / boddy flex....

i got to get this thing on a meter. does anyone have any idea where i can find a place to get metered in south east FL ?

06-06-2014, 11:27 PM
Nice!!!! :clap: I always wanted to try fiber glassing but I don't want to mess up my door panels but o what the hell I'll just buy some extra ones to practice on. This just gave me motivation.

dont fiberglass with out belt sander. lol
it will take forever to hand sand.

06-07-2014, 06:29 AM
**** well it looks like you had the same experience with the peel and seal as me:crap: oh well now we know firsthand

Whenever I fiberglass I just throw a 60 grit flapper disk on my grinder and touch it up. Works crazy fast.

so when is the wall going in....

nice truck, lots of room.

hopefully will have time to start this weekend - i wana lay out the floor first and then start building the sides. im building inside the truck / c pillar and going to try and utalize every single inch i can get in the hopes of having 60 cubes internal to make 4th order 2.25 to 1 ratio
but its going to be a slow build - as i have an amazing 6 month old sweet heart of a baby girl and she takes priority over most of my time haha...

alts in - took a few to figure out wiring - red and green wires needed jumped together and blue is remote turn on wire for alt. yellow does nothing on this alt. gota solder those and heat shrink the connections at work tomorow on lunch break.

something was keeping my voltage down at heavy draw - my front battery was weak - i un hooked it from the rear bank - and in 30 min it wanted to sit at 12.3 while the rest of my bank sits at 13.1 so i stole a battery out of the rear bank and shoe horned it up front on the stock location. i had been wanting to do this anyways for a bit now and needed a kick in the pants to get on it.

picked up some old school cragar sst 15x10 rims with my lug pattern 5 on 5 at a flea market local for 100 all 4 - had my spare tire ( same size as the rest of my tires just diffrent kind ) 31x10.5 mounted on one just to check fitment. i hoped it would stick out a little bit - but she is basicly dead flush with the sides of my burb.

wasnt shure if they would rub or not - but they do not - actually looks like plenty of clerence
also got singer alt installed - had my wet cell battery up front go bad - caused weird voltage issues took me a few to sort that out.
i un hooked my front battery from the rear agm bank - and in 2 hours it read 12.3 resting - while the front battery was still hooked to my rear bank it would read 13.1 still tho - so if your having voltage issues - i suguest un hooking all your batterys from eachother - and let them sit over night - then check each battery individualy with a dmm and see voltages. they should all be similar.....

went to my local skatepark i used to work at and gave demo to some dudes there - played a bit to hard and got the subs stinky and hot... need to pull them tomorow and ohm out the coils / visualy inspect for browning of coils... lol

amp under seat mounting position is also not ideal at this point - i noticed a bit more heat on the casings of my amps than i would of liked to feel...
maby they can mount on the front side of my c pillar wall that is about to get started tomorow i hope...

07-25-2014, 12:58 AM
got angry with my peal and seal deadner not doing a good job on the roof - so in my workshop i have a bunch of this thin wood
cut 3 layers thick to match the thickness of the roof braces up there

left a bunch of tar residue - extra terrible to scrape off with spatula - then mineral spirits took it completely clean - then scuff with 60 grit for "tooth"
http://i214.photobucket.com/albums/cc279/brian84corvette/031_zps45fc317d.jpg (http://s214.photobucket.com/user/brian84corvette/media/031_zps45fc317d.jpg.html)

all 3 layers went in at same time to "form" together. roof to first layer of wood was locktite pl adhesive. that first 18" section got a whole caulk tube
then the next 2 layers got tight bond #2 (http://www.caraudio.com/forums/usertag.php?do=list&action=hash&hash=2) poured on real quick and spread with bondo scraper and quickly put all up on roof and got the braces in place

http://i214.photobucket.com/albums/cc279/brian84corvette/032_zps6e48763a.jpg (http://s214.photobucket.com/user/brian84corvette/media/032_zps6e48763a.jpg.html)

second section in place - went in just like the first.

so the plan is to keep doing this to the rest of my roof - and once all the areas are filled with wood - then id like to do 2 or 3 layers of 1/4" plywood on the entire roof to tie it all together as 1 gigantic wood piece instead of a bunch of diffrent sections. hoping to completely eliminate roof flap / flex / noise and to raise the efficency of my subwoofers to translate all their energy to the pasangers inside the viechle getting demo instead of loosing a bunch of energy in flex...

mylows10 says if i were to compete - my wood roof would put me in an "extreme" class - but im ok with that.

At this point, why not drill through the roof and use bolts? Who will see the roof anyway? Put some silicone in there really good, maybe a layer of plasti-dip and call it a day.

07-26-2014, 05:56 PM
id be afraid of getting leaks in the roof by drilling holes.

you need some 295/50 white letter tires bro.

this is 1000% true ! ive been searching that exact size - have not come up with a tire that can take my load and psi requirments.
pepboys has the futura in that size can only hold 1800 lb per tire at 35psi max

my current michelin 31x10.5x15 tires on there are rated at 2150 lb per tire at 50 psi - and i keep them aired at 50 psi - yet they still seem to look like they are stressed to carry the weight of this truck - im afraid if i put on a tire that isnt rated to handle the load - or take high psi then it will look even worse - and or also be dangerous to drive on highway at speeds. i kno overloading a tire around town is a bit safer than doing 80 on an overloaded tire....
but yes yes heck yes - i would love to find a 295/50/15 that will take what im asking of it - or even a 275/60/15 would fit on and be pretty sweet.
pepboys had that 275 size in a tire rated closer to my load capacity - and took 44 psi is almost good enough...

my current michelin 31x10.5x15 tires on there are rated at 2150 lb per tire at 50 psi - and i keep them aired at 50 psi - yet they still seem to look like they are stressed to carry the weight of this truck - im afraid if i put on a tire that isnt rated to handle the load - or take high psi then it will look even worse - and or also be dangerous to drive on highway at speeds. i kno overloading a tire around town is a bit safer than doing 80 on an overloaded tire....
but yes yes heck yes - i would love to find a 295/50/15 that will take what im asking of it - or even a 275/60/15 would fit on and be pretty sweet.
pepboys had that 275 size in a tire rated closer to my load capacity - and took 44 psi is almost good enough...

build a box to replace the one holding 4 pearless mids up front center... currently holding pair of selenium 8w4p together for 4 ohms load bridged on mb quart discus 1k
so they get up to 250w each - they play 100hz to 4k hz with AUTHORITY i have them crossover sloped at around 100hz at 6db and at 80hz at 12db so intentionaly they do not play below 70 with any power. the 12" behind there take care of the 60 to 300hz range
more zebra sticker - somehow i like it
its terrible - but ooohhh so good at the same time lol

now im tempted to try the pearless 6.5 mids in my door pods... even tho ive been wanting to get some sealed back mids for there like american bass 6.5 i hear those take the 300hz up to 10k hz with authority... thats what im wanting my doors to play for good left and right staging in the upper hz range

finaly found a site that has some si ht 18 d2 in stock - ordered 2 more - were delivered by fed ex today !! woooo
the ghetto burb will be running six 18s in a c pillar 4th - roughly 2 to 1 ratio - 3 cubes net each sub for 40ish hz sealed reasonence
now i need to figure out the port.

plywood roof is in progress - ill snap some pix of that today. with even 1 sheet of ply up on the roof already it feels alot more "intense" as there is much less wasted subwoofer energy in roof flex. double thick with beauty pannel on the sides should be verry efficent at transfering subwoofer energy up front to the pasangers

i cant wait to pull nasty hair tricks

my port configuration will look like this - while keeping the second row bench up right for pasangers.

seemingly the port might end up being 16 to 17" tall opening by 45 to 48" wide and a few inches deep
not 100% on woofer placment in the back - as i dont want to fire directly out of the port with the top 3 subs
might angle it some how - still playing with ideas

08-23-2014, 12:20 PM
finished attaching plywood to my roof last night. its 3 layers thick in the c pillar back area - and 2 layers thick fowards of that.
plywood roof = arm death and stress

also got my floor built double thick now - and am going to start building the side walls next
either double or tripple thick on the side walls not shure yet we shall see how double feels

im actually screwing and lock tite pl adhesive the wood to the sides of the truck to get every inch of air space used that i have avalable back there. should end up with 65 cubes internal once the outside box structure is built - and hopefully the sides of the truck will act as a steel cage .... i mean maby the truck will flex a tiny bit - but with all that wood attached directly to it - i dont see the ability for it to move much...

08-23-2014, 12:40 PM
its getting there. but dam 6 - 18" dammmmmmmm . what amps are you going to use ? and what the rating on the subs ?
great work....

08-23-2014, 12:53 PM
single sub amp = ddm3a subs are dual 2 coils - wire to .66 ohm load at the amp.
each sub is rated at 600w by the factory - because they are built with loose suspension - the coils can take 1k rms power - but the suspension is so soft that they dont need that much power to reach full throw in and out - and are limited by the voice coils ability to move so far in and out that it hitts the inside of the motor at full x max on the rearward swing. because suspension is so soft = efficency build - and small box requirments.... each 18 only wants 2.5 to 3.0 cubes net on the sealed side of things to keep mechanical throw of the sub in check...

its an experement of large scale. efficency is my goal. do the most with the least... in my case - the least is power. wattage / electrical
i see no need to feed a super stiff sub 3k to get the same amount of cone movment as the soft subs i have that only need 600w to do the same thing.

big scott
08-23-2014, 01:11 PM
wow thats a good point. so a sub with stiff suspension will NEED more power to get it moving. never thought of that, but makes cents.
hell my hdc3 15" is still stiff as helll .

man i hope it all works out for you, and ill be keeping an eye out on this build. really makes me want to do a wall... but ill be happy with a big *** box for 4 15" lol..

super rough idea on port placment and sealed box placment - i like the port being where the small folding seat back was - as that can still be used as a seat - and the bottom of the seat is still there - so theoreticly it could be the hair trick seat - or tap out seat lol

2x8 bracing to keep baffle wall from flexing.

now i need to tripple up the baffle wall - and then add another layer to the loading wall - and then seal up the back by the rear doors
and then figure out how to tune the port ( how wide the port needs to be for tuning )
or just make a few diffrent sized ones that can quickly screw on and swap out for when testing hz begins

08-30-2014, 01:13 AM
you are crazy ! love it!!

08-30-2014, 01:39 AM
I would really like to see more than 2 layers on those long sides. Flexing box = a ton of lost output.

I would really like to see more than 2 layers on those long sides. Flexing box = a ton of lost output.

sides of what ? the truck - or the sides of the box facing fowards and rear ?
the plan for fowards and rear is to add 2 layers of plywood - and then come on from the other side with 2x4 bracing ( notched out for seat back as well ) all along the baffle wall and all along the rear by where the back doors are.

the sidewalls of the truck - the wood is actually screwed to the truck - so if flex is going to happen there - the entire truck will be flexing not just wood... and i was pretty heavy on the locktite pl adhesive when applying pannels - but i do plan to get some custom bracing made to go across and keep things tight.
i would like this build to play 150s minimum and have a good range of hz in 150 - so thank you for the tip !

I'd be trying to do ANY SIDE wider than a couple feet with 3 layers of 3/4 ply plus some bracing where possible. From where you're sitting, it looks like space isn't really an issue, and the cost of adding a few more sheets of 3/4 is really negligible. It'll be a whole lot easier to do it now than to find walls flexing later and try to Band-Aid with bracing. I think that the baffle will be OK with that window-pane of 2X8 but 2 layers plus some really thin sheet metal is pretty dicey with such large walls.

I will never forget building a box with 2 layers of 3/4 MDF in 1996 for 6 12" JBL subs (pretty entry level at the time). On about 800W total the 1.5" MDF was flapping around visibly People, I think, grossly underestimate how much pressure a box with this much cone area will build up even without a lot of power.

08-31-2014, 03:38 PM
as for the side wall flex - i was curious about this yesterday - so i got inside and put my back against the baffle wall - and tried pressing my feet against the plywood wall on the pasanger side of the truck. i kno i can do 400+ pound squat thrusts so i figured if i cant flex this wall with my legs then the subs probably wont either.
im confident that its sturdy. what you dont see behind the plywood - was 2x4 bracing pieces that i added in the spot where my window goes before i put on my first layer. since i was testing flex - i figured id put my feet on the roof - and try and flex that to see if it had any give also... again - its just as solid as can be. there is so much wood in my roof - and tubes of locktite pl adhesive applied in the roof its not going to move anywehre. id be suprised if i even needed a stripper pole vertical because its just so solid....

all subs are in - wired up my amps = one of my 4 chans ( mb quart discus 4125 ) decided to start a fireworks show inside its heat sink :(
still have a good one tho to power my front doors and active super tweeters... tossed in a old schooler rf punch 400a4 to power my midbassers.

still no headunit
still a crappy crossover
tried using a line driver but it introduced ugly ground noise to the system... so not using that
it plays
and sound pretty rad... its loud also. like silly loud - draws a croud whenever turned up ( gain knob for ddm3a has clipping indicator ) so i kno how far i can turn up before playing dirty signal is pretty nice feature actually.
dang its loud. its just brutal to sit in - plays the range pretty good - and digs nice and low.
now i just gota do the finishing touches
buy a headunit - I HAVE NO IDEA WHAT HEADUNIT TO GET ! please recomend me a good single din with good pre out voltage rca
id buy the pioneer 80prs but the only thing selling it to me right now is the 5v pre out rca.
