naw take out the rear trim panel in between the rear speakers (its carpeted). Then i took and built the sub box all the way to the back wall. its all out of mdf, then i covered it in the same color tan as the carpet so it blends in well. i have two full size subs in there the fit well and hit hard. Good luck with it! they are the 5 5/8 deep you have the room to do anything!
