When I turn up songs with a good amount of bass my door speakers cut out. From time to time the bass comes back. These speakers are brand new and I'm wondering if a channel on one of the amps is bad?
Are they factory replacement speakers? If not then the problem is that aftermarket speakers are 4 ohms and the factory ones are 8 ohms. The lower impedence messes with the amps at high volume and they cut out to protect themselves.
