I had a lot more free time in college than I do now. I spent four days one time wiring this backboard of my single cab Dodge up and running speakers and subs everywhere I could. Old stereo equipment rules. The new stuff just doesn't have the quality sound of the old Alpine equipment in my truck.Above the stereo board, you'll notice a 1-inch tube running from the left to right of the cab. Wilcox also helped me weld that in so I had a secure and proper way to run my 4-point harness seatbelts since I did not yet have a rollcage in this truck.
