Hello everyone, I’m new to car audio and I just recently bought a car and I have discovered a new problem with it. It is a 2008 Jeep jk with the infinity sound system. Now here is what is happening, when I turn the volume up, the subwoofer cuts out but none of the other speakers. The only thing that has been done it is an aftermarket head unit. I have not taken a look at anything about it, but I wasn’t just wondering if anyone could point me in the right direction of where to look first.
