I have the same problem. I believe the M2 doesn't put out enough voltage to power my 2 amps.. I have the remote line hooked to an IGN wire so I get the pop..
Has anyone hooked up a relay and did it work?

Pin 86 - Connect to Ground
Pin 30 - Connect to constant 12V
Pin 87 - Connect to Remote line going to amps.
