Hi I want to build a sub box for my 86 gmc,
but having a hard time to find the right dimension
so if anyone has them I would really appreciate
if i can get them.
Thanks

8", 10" or 12"?

I have some q-logic boxes (two boxes) for 12".
The dimensions are:
Length 25-1/4"
Height 15-1/4"
Top Depth 5-1/8"
Bottom Depth 7-3/4"
These boxes also have holes cut in the rear with a steel cup installed, which allows for deeper speakers, gives about an extra 1/2", which is just enough to fit standard size 12's in there.
If you build a box and need just a little more space for the magnet, you should be able to find the steel cups from a local sterio shop.
I bought some from Circuit City for a different setup.
I can get a picture of the cups if you need, send me a PM.
These are nice boxes with good sound, but require the seat to be up 1-2 notches from all the way back.
So it limits your leg room a little bit.

depends on the sub size single or dual voice coil and so on i know my box is 4 top and 8 bottom for 4 12's
