Question about Alphasonik PMA600HC Car Audio Amplifier
The soft start on a amp keeps the speakers from popping when you turn it on, I thought that it would do the same when you turn it off..It sounds like some kind of surge..It is only this amp that is doing it.. The Eclipse amp running the highs is not acting up..This amp is brand new and the head unit is also..
Most amps come with a soft start up that illiminates this problem... Im guessing that your amp does not have this feature and thats why you hear it. Read the manual and see if it states anythign about this.

It's likely the amplifier but defective speakers or having speaker wires shorted to ground can cause strange problems also (depending on the way the protection circuit responds).
Disconnect the speakers from the amp and connect a speaker that you know is in good working order. Use a speaker that can handle a lot of power and be ready to switch the amp off quickly or disconnect the speaker wires from the amp in case the problem is in the amplifier (you don't want to damage the test speaker).
