Anyone happen to have one of these thats lying around and works? Im just wanting to replace and not upgrade the sound at this time. Kinda sucks having it back there and not working. To my understanding this is a common failure? Also to my understanding that if the head unit works then the sub amp should as well since Im told they share the same fuse?
Dont know much about the mach systems but, there is a remote wire that should turn the amp on when the radio comes on like a relay. But I would think that it would be rare that something would happen to this wire unless someone had had the amp or head unit out. Try checking with a trouble light or a volt/ohm meter and make shuer you have power at the amp first before you replace.
