Bought my crossfire used. It had an Alpine head unit in it-no bass at all. I recently decided to purchase a factory head unit to put back in. Whoever previously installed the aftermarket Alpine had cut out the factory wiring harness that attaches to the back of the head unit. So I had to order a wiring harness. I now have everything hooked up except a pair of blue and a pair of yellow wires, which according to the diagram, run to the amp. Where do these hook up to, into the harness. I currently have no sound/bass from the rear

 

I can't make out the colors( stripes)on the wires. On this forum, you can down load a service manual, for your vehicle. Section 8W-47-pgs1thur5. YL an YL/VT is radio to amp left/right rear speaker. BL an BL/BR is radio to amp ,right and left door speaker. Hope that helps

 

What Alpine did you pull out ?
Wanna sell it ?




radio wiring

 

It's the braided yellow/yellow-violet and the blue/blue-brown from the diagram. Coming from the amp. I don't seem to have enough wires in the radio side to hook them to. Unless they share another connection

 

Question! Did you buy the factory radio, you talked about in the first post or is it the Alpine you removed and are trying to reinstall? Ala_fire posted the factory wiring diagram, from the manual, for you. I hope that gives you a better point of reference. What color is the 3rd yellow wire in your picture?
