I just got my system installed. When I turn the key to "on" the head unit turns on as it should. Just as soon as it does I hear a very loud "Pop" or "Thump" coming from my speakers. I've had the head unit for a month prior to getting my amp and other equipment installed and I never heard this sound before. What can cause the loud thump and how can if fix it? Is it damaging my speakers?
Here are my specs:
Alpine CDA-9831 Head Unit
Polk Carbon C400.4 Amp
Polk Momo MM2104 10" sub
Polk Momo C570 Door Speakers (Front)
Alpine Type S Door Speakers (Rear Fill on head unit power)
