Believe it or not the sub enclosure is removable. It is not tied down at all. the weight keeps it from moving. The covered panels are removable via velcro. I remove 4 screws on the back side facing the rear seats and the cap comes out with all the wiring. The subs and neon use quick connects so i can disconnect all wires within seconds. But given its weight, it would require 2 people to move it out.
I removed the two "pockets" on top of the wheel well and screwed MDF to the wheel well. The amp is then screwed into the MDF. A trim panel was made to hide the amp wiring (pix below).
Because of the way our rigs are wired, if you remove the headunit from the rig many things will stop working like memory seats and a bunch of other stuff. So we moved the factory HU to the rear and strapped it inside the wheel well panel on the passenger side. More than enough room there.
Yes I did replace the speakers also. Actually gutted the truck - removed all the seats and carpet because I also dynamated the truck. Anyways, I used CDT Eurosports all around. All of them were components. Onstar is a pain the rear to deal with. A reall pain. Plan your work carefully before ripping things out. It's not like other cars. these rigs use the factory radio as a "bus" to distribute many signals required to make the truck work. Sucks in my opinion. I am told in the next few months a few companies will offer a breakout box that will allow us to regain the steering wheel controls for the audio with aftermarket equipment and allow us to ditch the factory HU.
Hope this makes sense.
