A few sub box designs for everyone to use :) - CarForum.net - Car Forums, Automotive News and Community

Hey guys, I was digging through my old data on the computer nad found some really good old box designs if anyone is interested

**THIS IS NOT A STREET BOX!! DO NOT PLAY MUSIC THROUGH THIS DESIGN!** This box is a competition box only, and WILL NOT play music...well, it WILL play music, but your sub will unload and basicly tear itself apart. This is a burp box meant for dirty SPL.

This is the design I built for adas, and is very similar to the box that's in the video in my signature, and it's a great street box. With my Resonant Engineering SE 12", and JBL BP600.1, I hit my max SPL of 140.7. In the competition box, I achieved 147.3

Feel free to use 'em

Damn, 140 DB, did your ears start bleeding? Did you use mdf or hdf?

3/4" MDF for everything

Right now im in experimenting with linear equal ports...ones that achieve the same x and y axis thoughout the box, and doesn't gain size in the corners.

Anyone uses these designs, lemme know how they worked out for you

Have you ever build a box for a del sol to go behind the seats. I think their would be room if I removed the two glove boxes and hacked the center console. just wondered if you guys have a standard design. I have a friend in vegas who is willing to build one for me but I think you have more knowledge of accoustics. I would prefer a sealed box 2 or three subs if 3 subs I want one 10 and two 12s. or maybe even a step down to two 8s and one 12. In some of my older systems I found that my 12s had trouble with a certain reverse base sample that is common in Drum and bass music. I will need some extra clearance on the sides and back so that I can cover it with fiberglass later to blend with the car. I live in phoenix and drive with the top down alot so all those theives would be quick to try and jack my car. But now that I have 3 kill switches they would try and get the box, or the subs. I plan on bolting the box to the center x brace and then fiberglass over it. I also plan on filling in the screw heads with epoxy after it is complete. When I blow a sub it will suck to change it but I should be able to handle it

.
Any ideas? I forgot to mention I am going for reproduction not spl. I also want to preserve symmetry. no lopsided speaker setup even though I know. I could make the same size grills.

When I was building boxes for people, I always needed to see the space that I would be installing it before I said anything about it. Can you get me some pictures of what you mean? And possibly some measurements?

EDIT:
And in my personal experience, running different sized subs in a vehcle *generally* give an odd sound.....but if we can manage to give the two smaller subs a a seperate chamber than the larger sub, it should be alright AND you'll need to run two different amps OR two seperate EQ's so that we can seperate the the frequencies the different sized subs will play. You'll probably want the smaller subs playing 100mhz+ frequencies, with your larger sub playing the sub 100's...namely somewhere around 80ish.

Honestly spooky, I'd go with 2 10's or maybe even 3 8's, depending on what your space allowance is

I already thought of all that. I dom't know if you know but I work on large concerts and such, often having electronic crossovers that have 4 EQ bands. Low, low mid, mid, and high. I am not sure what I can find to do this yet. At work I know the exact equipment but not for my car

. I am going to look at some options. I am now thinking about 2 12s but two 8s at the kickpanels if i can fit it next to the clutch petal. I dunno yet. I just wanted to know if you had anything specific from a past install disigned.
