Need a dual 12" box for my King Cab

Beaker · 09-19-2005, 08:01 PM

I just aquired a pair of free MA Audio MA1211XQ's. They seem decent; dual 4ohm, 800w. I am not sure about the mounting depth (their website doesnt say for this model) but the 10s are 5.6" and the 15" are 6.6" so I assume about 6" would be adequate. I need 1' cu.ft. give or take.

I've seen a lot of people who have made their own boxs, but who makes a pre-fab box to these specs? I've seen some pre-fab'd ones on ebay, but they are all for crew cabs and are for 8-10". I just dont have the time/resources/skill to build my own.

Let me know, Thanks.

free is good. if they suck you can't lose and you can sell them for a profit.

you should be able to measure from the bottom of the magnet to to top of the round basket where it would sit in the box. it's recommended to give about an inch of space for the magnet.

The problem is not the size of the cutout, but the fact that you need 1 cube per speaker of air space. Most boxes that you would build under the seat only have .75 cubes of air space. Based on my calculation, you could possibly build a box out of 5/8" MDF that would have 1+ cubes of air space per speaker - but there would be no room at all for mounting amplifiers or anything else (these would have to go under the seats.)

This is my diagram I made for installing 2 x 10" subs with .75 requirements along with 2 amplifiers:

You won't be able to fit 12's under a kingcab seat nicely. They will have to stick out in the front by a good bit and will probably raise your seat up a good bit. I think that even 12's in a crewcab are a tight squeeze. If you measure under there you'll see what I mean.
