I used an LC2i LOC and tapped into the rear speaker wire. I also used the blue/white wire from the rear harness for amp turn on. I used an amp wire kit for everything else. The amp and sub work fine but now steering wheel controls are gone. How did you fix this one your Focus?
So after installing an aftermarket amp and sub, all the controls on my steering wheel including turn signals and wipers stopped working. I've gone through all the fuses and they're all good. Any ideas?
So after tons of researching, I'm still asking. What is the color of the turn on wire, say for turning on an amp. I've heard it's the blue/white but when I tried, nothing. I'm pulling from the rear wire harness?
