I am unable to get the front speakers to work on a 2007 XLT. After looking over other threads it appears I'm experiencing the same issue people have when installing an aftermarket stereo with a factory amp. When I bought the truck it was mentioned to me that it has a factory amp, but only for the front. The front speakers work if I plugh the factory stereo plugged back in with hardly any audio from the back speakers. With the new stereo there is absolutely no audio from the front speakers, but the rear speakers are much louder than with the stock stereo, which appears to be consistent with what I was told when I bought the truck. I did check the front and rear fader, so that's not a problem. I used a Metra 70-1771 wiring harness to wire it up to the Alpine. Alpine and Metra use the same colors on their wiring, so it's wired correctly. One thing I did notice is that the Metra wiring harness leaves out pins 2, 3, and 4. The harness in the dash has wiring for pins 2 and 3. I tried the remote wires on the Alpine on both those wires. It didn't activate the amp. Also, I'm unable to locate the amp. I've read it's mostl likey under the rear passenger speaker. Ford parts has a diagram that has mounted by the passenger seatbelt behind the seat. Someone else found the amp under the passenger seat. Another found it by the fuse box on the passneger site, and there was mention of two other locations behind the dash. I've looked in all those ares to see if I can locate the amp and maybe figure out the wire colors.
Does anyone know what wire or pin activates the amp and where it's supposed to be located?
