I am having an issue, today I added a 5 channel amp to power the stock kicker speakers. I have the Kicker KMC1 headunit and I chopped the speaker wires and instead routed the speakers to the new amp. I then did what should be the easiest part and ran RCAs from the kicker HU to the amp..Nothing..Silence, I know the amp works because it also has a PA mic and that works fine, and when you tap the rcas on the rca ports on the amp you can hear the speakers make a little thud. So I'm thinking maybe the preouts on the kicker HU are either not enabled or not working?
