Come back soon as I add more pics.
System will consist of when completed:
Alpine 7941
Planet Audio HVT 754
Polk MOMO 6.5" component set (custom kicks)
4 JL 12w3s (cab cut)
2 JBL BP1200.1
HO GM Alternator conversion
2 Optimas
My goal is to do step by steps of all the construction processes.
So, here is my Toyota I love this truck and it will eventually be a rock crawler but for now I am working on the system. The image on the left shows what the truck might look like with a "bobbed" bed, the lines show where I plan to build the exo cage.
The problem with Toyotas is they have no space behind the seat:

(don't worry those 6x9s came with the truck and they are long gone)
At first I was going to build a fiberglass box and put in just one 10" or 12" but I decided that wouldn't fulfill my goals, so I decided to do a cab cut or "blow through" as it is also known. So I enlisted the help of my friend Robert.
