noob question. i wanna buy a sub box but i dont know if i have a qc or a cc. how can i tell? and wat will fit under my seat? 10s? i wanna get sum good speakers but sum r too long and probably wont fit?

 

and wats better 2 12 shallow or 2 10?

 

There is only one 4 door cab to choose from in a 3rd gen, besides a megacab. Call it what you want.

 

10's need less air volume. It's personal opinion, but I like 10's in a truck. I think they hit harder, apples to apples.

Also, if you really can't tell, a quad cab has 3/4 sized rear doors. But like olyelr said, you'd have to have a mega cab to get full sized rear doors.

 

a single good 10 with enough airspace (like a foxbox) will hit nice, Ive got two full 12s in mine and obviously dont have enough airspace, and they dont sound as good as id like.

 

i have 10's in my QC and they sound good and hit hard

 

to answer specifically, with you having an 04, you have a QC.

Ive got two Kicker CVR 12s in a sealed Foxbox. There are pics in my sig link gallery
