ok i think i made my mind up on what i want to do... i think im going to remove the 40 seat the little seat in the back a and have a custom box made nothing fancy just a square box the high of the other bench seat then invert a rockford fasgate P3 12 with a rockford T500 mounted in the front of the box flush so u can see the amp i think that would be pretty cool and it would beat!!! or i could do a lift kit for my seats and get i think almost 6.5in of mounting depth but that setup from supercrewsound is way to much money

 

I did that very thing in my '04 STX. Worked very well. Was a bitch getting the back seat bracket bolt out, though.
