I basically did the whole floor and rear of cab wall because I removed the gas tank and have my sub box back there. The doors I did 5 pieces in each. 1 piece was 12"x12" in the center then 6"x6" in each corner of the door per my local radio shop guy. I think it made a huge improvement in the sound.
