    Default Sub Box Choices for 2003 Chevy Crew 1500 HD

    Alright, so im surfin the web here trying to get some ideas for a box for my truck. I want to get two 12's in there at some point this coming summer. The two options for boxes are under the backseat or behind the backseat.
    Now heres the dilemma, ive found a bunch of nice boxes for both, mainly these ones:

    http://www.halfpricecaraudio.com/Che...2X12CREW07.htm

    Now both of these are for NON hd trucks. I think thats a complete load of crap and i think that they should be able to crossover, but i cant find anywhere online saying that they do or dont. So can anybody give a definitive answer with some support on the subject?

    Thanks guys.

    Check on E-Bay you can find the box custom made for your truck. For I have a 2004 Z71 Silverado Extended cab. The enclosure fits under the rear seat. It has 2 800 watt peak 10" kickers in it. I believe you can get 12's also. The E-Bay seller is Q-Logic or just search E-Bay for the enclosure. I just installed one with a Kenwood 1000 Watt Amp... The box was 259 plus 20 for shipping and the amp was 145 with a wiring kit that you can also find on E-Bay.......

    Sorry brah. Ive been talkin around alot with some of the guys that i know, alot of people are telling me that they didnt make a whole lot of 1500 heavy duty crew cab trucks back in 03, thats probably why its hard to find any enclosures for the backseat. Considering i havent even found one that has the right dimensions yet ill probably just build one myself. Better learning experience.
