i got a power acoustik amp class D gothis series 2000 watt. well when ever i turn my car off the amp should turn off to , but all of a sudden it wont do that now, when i turn my car off it remains on.}
Are you using an actual remote wire or are you using an automatic turn on/off feature built into the amp? You say "...all of the sudden it wont do that now..." did it used to shut off and has now failed to do so?
