It’s well documented that when the Mach 460 gets older the amps can fail in a way that causes a parasitic draw on the battery when the car is turned off.
What I have not been able to find is anyone documenting what fails in the Amps and if they can be fixed. I have found a number of repair threads and video for when the Amps fail completely but nothing on the parasitic draw.
I don’t want to have to replace all the speakers, wiring and amps. I just want to keep my Mach 460 systems running (I have 4 cars). Has anyone found a solution to fixing these amps? If I can’t fix them, then I may have to run a relay to cut the power off from them when the car is shut off.
