2004 Silverado wire colors
I've got a 2004 silverado ext. cab with the Bose system. I've added an amp and two 10" woofers, but I'm a bit stuck. Everything is wired up and the amp powers on like it should (read no sparks or fire). But I get no sound from the speakers. I have a line converter, that I used to tap into the factory wires that run into the bose amp. I spliced into the wires just before the wire harness that plugs into the bose amp. The wiring is secure because the bose system still runs fine. I'm wondering if I spliced the wires incorrectly - wrong colors. Does anyone have an idea of what color wires are the right/left positive/negative?
Thanks in advance for any help.
