Amplifier install causes POP through speakers when turned on.

I just installed a GM-D1004 Pioneer amplifier alongside a ISO T-harness that allows the system to be wired inline with the existing car speakers. However, doing so has caused the a loud POP sound to come through the speakers when the car is unlocked (I believe this is due to the fact that the AMP and the head unit turn on at the same time). I was hoping that someone might be able to shed some light on the situation.

I have thought about wiring in a switching wire that doesn't pull from the head unit, except that would completely ruin the plug and play functionality.

Any tips would be awesome.

Cheers
