5-6 cubes ported would be good, preferably 6.

Go to kicker's website and see what they recommend. I would go with 5 cubes or so. You have plenty of power so a really big enclosure isn't necessary.

4.5 is the biggest I'd go. The bigger you go the more output you lose.

I have one in 4 cubes tuned to 38hz. It beats hard in the tacoma. Dash moves up and down about 1/2 inch on some screwed and chopped songs. Steering wheel shakes. Doesn't sound that bad on rock songs. I had one in 6 cubes tuned to 32hz. It beat much harder in a ford explorer.

Ok well the re calculator said the volume is 5 i assume thats total before woofer how much do i loose with wood and sub and what not , hard deciding how big to make it as everyone says something different, and should the port be 3.5 4 4.5 how wide what is the difference is sound ? and the l port wall how long should it be and does that affect sound much right now it's at 10" and tuned to 28 i wonder if thats to low

im gettin ready to start my box next week so i got in touch with a kicker rep and he said to tune it at 32 to 34hz. your box looks almost identical to mine, 28 width,18height,22depth,4x10 port 33.56hz. i may make my box a little taller and wider like yours hopefully someone will chime in and give us some info

A really large box is going to play flatter and be more musical, but you'll sacrifice output and power handling. However, you'll gain efficiency.

There's really no point in tuning at 28 unless you listen to nothing but songs that peak in the 30's.

on1wheel01
02-06-2009, 12:53 PM
ok but now my main ? is how wide to make the port 3,3.5 4 4.5? my last box was 3.5 and how long to make the port wall length (the l bend of it )is 10" good shorter longer? and how much affect does tboth have especially on tuning and sound

02-06-2009, 01:06 PM
Ok well i did some more playing with the re calc and may just go with 30 langth 22 high 24 depth port width 4" and length 10" volume of 5.8 i guess that would be around 5 at the end i think 29.37 freq not to bad i guess

lowrnu
02-06-2009, 01:37 PM
yea im not sure on what would be best as far as the ports width? why dont you go ahead and build that box and let me know how it turns out lol

02-06-2009, 01:54 PM
lol yeaq ill prob just go ahead but my acura wont get here for another week or so so i've got some time to make any last decisions i've gotta measure my truck and be 100% sure it will fit. Unless somebody has a 97 style acura cl and wants to measure for me lol

i wouldn't tune it that low with that sub. your box volume is fine, but i'd tune it at least to 32, probably even higher. maybe 36. kickers seem to do better with a higher tuning.

40 sq. inches of port isn't enough with 5 cubes. i am assuming that your port is 4 x 10? any way to get 60 inches of port and still fit it in the car?

Ok not sure how to tune it higher, help please lol

you need to redesign it. in 5 cubes, i'd do maybe 12 x 5 port (inside dimension). that makes your box 13.5 inches total height. will that high fit in your trunk?

on1wheel01
02-06-2009, 04:42 PM
I think i am confused the height of the box right now is 22. I may be misunderstanding you( im sure lol) Would a 5" port be to wide>?

ok well i found out my trunk is only 16" high. so here is the deluma should i make the box 14" high and have sub up port back. or have it 16" high and try to get the sub facing back with the port back also. the width is 36 and may do 20 inches deep to try to get more volume as with 36 14 22 22 port width 5 and l length 6 is 4 cubes 33.6 hrz small i know but i need some trunk watcha think sub up or down

I would put the sub and the port on on the same panel, and bump the box up to 16 inchs. but that is just me.

what's up on1 wheel? this is mattastick from Azine... the one I'm working with right now is going to end up around 4.5 after all volumes are taken out, and it's tuned at ~32hz with 58sq in of port area... should hit like hell, but I dunno too much about this sub, so if any experts can chime in and help out with tuning or whatever, that'd be great...

What up man. that would be about right i'd like to have her tuned a little higher but hey it is what it is. I'm hoping i might be able to get it subs back but if have to subs up will work

Well just finished up building the box, waiting on the sealant to dry. Ended up building it 36" wide 14" high and 22" deep. Port width is 4.5 ends up having 4.32 cubes tuned at 33.9. Ill post pics in a bit. Once dry and all I am going to rhino line it. I think I could have done a better job but I am happy with the results.
