View Full Version : GM extended cab trucks

I have an 04 extended sierra and is there anyone who has found a way to fit a 12" sub with 10.5" mounting depth in that type of truck without removing a seat for the box etc...

maybe do a forward firing with some sub rings. I fit my pioneer 3004spl under my 97 ex cab silverado, it has a mounting depth of 7.5-8" iirc

i was thinking forward firing but i dont want it to stick out to far...

you MIGHT be able to squeeze it in there doing an upfire/downfire, but you'd have to raise your seat a few inches, look over on fullsizechevy.com to find the brackets
