Im gonna build it myself.

 

alright can you wait until this weekend for some diminsions? The only thing I would watch for is if you have any large friends sit them in the front cause there is nothing under the seat to prevent it from touching the speakers. Isn't **** for room.

 

yea i can wait just post it or message me. thanks for the help

 

i think you would be time and money ahead buying a box. i purchased mine off ebay
from competition audio. im running 1 arc audio 10" and arc audio 5150 amp. pionier
speakers in all the doors. i should be installing the sys this weekend. the box is 59.00
plus shipping. the volume is .73 cubic feet and will fit just about any ten.

 

im looking for dimensions to build a sub enclosure for 2 soundstream 12’s to go under the rear seat of a 2003 dodge ram 1500 quad cab. Can anyone help point me in right direction please?

 

Erm, 15 year old thread?????? Really?

Why not measure the available space, and go from there?

 

yeah, old thread. I think you'd get better info by describing your project and goals in a new post.
Lots of considerations in sub box construction. Are you going to remove the fabric insulation under the seat? Ported or sealed box? Using one or both sides?
I've had two Gen3 Rams and installed a sub in each one, using different methods. One time I removed the fabric and formed a fiberglass box with an MDF top. The second time I measured and built a wooden box without removing the fabric. For the wooden box, I had to extend the free space into the middle of the seat to get the box volume that the sub required. Sealed boxes sound better in my opinion and take up less space, just need more watts.
