One week later.. And I put a system in. I couldn't handle the no bass stock stereo.
You can't see it, but there are eye bolts on the side of the box and turnbuckles holding it to the cargo hooks. So no drilling to keep it in place.
Groundshaker Bandpass box off of Ebay brand new for $70. 2 Apline E-Series 10" subwoofers from my old box and a 600x2 Kenwood amp from 1999 that just won't die. (It was my brother's amplifier)
I used a RCA converter off of the drivers front 6x9 (Gray-yellow and gray-violet wires in the harness to the door) and used the rear 12V adapter for the Remote since it is switched on the RAP system.
Don't mind the mess, I vacuumed it after the pics.
