I have the Rockford Fosgate OEM system in my outlander. it has intermittently been cutting out where it just seems like the amp loses power. if you turn the radio up to 40 you can hear it. there are no error messages, no pops or crackles, just on one minute off the next. sometimes a bump will make it go on or off, but for the past two days its just been off. dealer said it might be the amp which would be $1200 "if I'm lucky". Is there an aftermarket option, possible loose connection or other? I have an appointment with the dealer for a more specific estimate, I guess I am just preparing for the worst
