Hello folks, I did a search and couldn't find the answer from any of the old posts. So here's my problem. Since my car has the Hi-Fi system built in, I initially replaced the head unit and used the existing amp and speakers. That worked fine. But I now I changed the amp, and used the existing wiring to the speakers. The rear speakers work fine, but the front wont turn on at all. What could prevent the fronts from turning on?


Thanks,

Ken

So you installed a 4-channel? What kind? Just guessing that it's on the amp settings b/c the head unit and speakers worked in that config before you swapped amps...
