issues with ignition control module and ignition coil

Hello, I would consult a car audio specialist to get advice on this. There are several around, and several searchable via the Internet. It is entirely impossible to know much about what to suggest since we cannot examine the wiring set up for your aftermarket components, or even guess at how to rectify your concern.

This is a rather unique situation - Can you enlighten us as to how that conclusion was reached? Normally the amplifiers main ‘current’ supply is drawn directly from the battery - not the ignition. Of course as stated - we have no idea how this system is set up. Google > Crutchfield - - free technical advice from the best in the business! Good luck!
