MATCH PP82DSP - Thump when amp turns off?
Finally got around to installing my Match amp today. I noticed that after I turn the car off, and wait a little while for the electronics to actually turn off, the speakers thump. Is this expected for this amp? I'm using a bimmertech harness (with power and ground from the harness)
