Looking to see what y'all think of running a custom 12 (4hp motor) on 3.5k to hit a 148 or higher. Looking to tune at 38 and it will be in a trunk. Also thinking of putting it in a 4th order.

it can be done. theres a guy in the org on compete in that does a 148+ from the trunk with 2 10s and i think 3.5k and on music and not in a 4th order. i have no douts that i can be done

anythings possible with enough money for the right equipment!!!! 38hz seems a bit high though... 32hz? well maybe not? I'd be interested in seeing it....

It took me an 18 with the 4hp motor and almost that much power to get to 148 from the trunk, but at 30hz.
Its going to be a bit harder with a single 12 and that low of a frequency.

its possible though!!! what kind of trunk are we talking though, my whole trunk is open, both seat fold completely down, or are we talking sealed off trunk? murph what kinda trunk ?

Tuning that high for a reason...

Yeah I figure it will be a pain but I'm aiming for it at 37-40hz so that will help. I figure if I can get the right 4th order it could happen though.

My seats fold down so that is not an issue. Room will also not be an issue for a single 12 I can comfortable fit 5 cubes in there.

its easier to get higher numbers with higher tuning

yeah, thats why i said maybe not, with factors tossed in there with the difficulty from the trunk, 32hz daily driver status!!!!
I looked up single 12s and there some guys doing it, and a guy with a kicker sub, 141. From the trunk, lol i think he's lying no video proof! Lol

A 141 isn't very impressive assuming his kicker is probably at 45hz. I want a setup for competition that I can still enjoy. A box at 38hz is plenty enjoyable. I can play down to around 30 still at that tuning

he quoted 39hz, i don't believe him though... I haven't heard a good kicker in years, it was on that stevemeadedesigns site.... Did you ever go over there and check out all the little sh*t you can do to up the db's, its crazy, like a list of 20-25 things, little stuff i never even thought of!!!

Sooooo many factors. But totally doable.

I'm not new around the block there is something like that on here also or was...

I think I can pull it off. Definitively will not get 150 without a fart box. If I get a 148 I will be happy.

You may end up needing to make some concessions- namely peak freq and/or musicality, but shouldn't be a problem. Unless the meter just hates your car.

im curious does this guy have a trunk wall? or whats his sub/ port variation if you happen to know.

subs forward, port forward. No wall actually. the box comes to the inside lip of the trunk so its all the way in there and no wall.

You will run out of x-max before 148dB if you are trying to tune that low with a single 12. 38hz tuning is typically way too low if you're trying to see good numbers with small cone area.

la_crx did a 150+ on a dd z 12 and a dd m4 iirc. There's a video of it, in his saleen mustang :cool:

I think it'll take more than one box to get it there. I'm not sure if a 4th order will get you there either. It also depends on where you meter at. Kick usually yields higher numbers than @ the headrest. But 3.5k and a single 12 is doable. Look at the "spl gains" thread over at smd, best thread ever. Good luck man!

i know this is late but no trunk wall. he did these numbers with Zv3 10, now he has 2 10" Zv4's with i believe a 8" aero. both firing forward into the cabin. and im sorry he has 2 sundown 2500d's. so 5k....

My wifes focus does a 143.8 from the trunk on 30sec music average with 1 L7 15 @ 37hz.... 141 is really not high at all, i mean 143.8 isnt high either but she's happy with it lol

I did a 148 @26hz and a 150 @32hz in my trunk. I did a ton of testing though...

your wife has a 15, and dude's kicker was round, so not a x, l7 or l5, thats the only reason i don't believe dude, looked like best buy kicker, lol theres alot of factors but i know it can be done!!! i don't remember what he had it tuned at neither!!!

Too much fail here... Referring to some of these responses

But to reiterate the good advice, it can probably be done; testing is key. Build a box first to your musical tastes and see where you are. That way you know it'll be satisfying to listen to. Don't slack on electrical/deadening/all that good stuff, too.

I'm not building a box for my musical tastes with one 12. I want to be able to enjoy music with it that is all. Probably will go with a 40hz tuning. I have a **** ton of cld tiles left to use. I know what to do all I was asking was for people's opinions and higher level help than talking about electrical.

thanks foe reply. eight inch aero seems huge for two tens. i wish there were more trunk set ups around my aerea that can get down. there the most interesting in my opinion.

I realize that. I was talking about some of these comments like "hey I know a guy hitting a 140 with a kicker 12"

I may have missed it, but what car is this going in?

148 is no joke, and with a single 12" would be quite impressive. I'm still working on a 145 with half that amount of power, ha.

Another question: what's the metering location? In MECA we're metered at the headrest and 148 is a **** high score for a trunk for the headrest

Chrysler 200, the seats fold down and it has a decent amount of trunk space.
