I just installed a Pioneer p3800mp in my 98' 1500 4x4 I used the wire harnesses the shop gave me which fit perfectly, I hooked all the wires up to the proper spots and now even if I try to run the front side off the rear channel I get absolutely nothing, it's not faded or anything what the hell did I break?

 

You didnt hook up the factory amp.... There have been about 6 post regarding this in the last 2 weeks. Connect your remote turn on lead(blue) from the aftermarket unit to the white factor wire. http://www.installdr.com/Harnesses/DCP-Wiring.pdf

 

I don't have the infinity stereo though, and I can't find any white wires...

 

well.... They do the back speakers work?
