Recently my sub has started to "hit" when I turn the ignition on while the cd loads. I thought perhaps it could be a grounding problem or amp problem, but really didnt think much of it. Then I realized the sub started making a popping sound and distorting quite a bit at around 2/3 volumes at certain times(but not all the time). I really haven't taken the time to take a DMM to anything, but the other day a buddy of mine was riding with me with the volume low and he pushed the cigarette lighter in and the sub POP'd quite loudly..the wierd thing was that the entire head unit shut off and reloaded. I have NEVER heard of anything like this happening, but I have to believe it's an electrical problem. I really don't know how to go about solving this..I suppose it could be various things. Any ideas as to what it could be would help. Thanks

First thing i would check would be all the grounds.

I would check all connections to make sure they are tight and secure.

Next thing I would do is to pop the head unit out and look how your RCAs are ran... Wrap the exposed metal part of the RCA with electric tape...

Also make sure its running 90 degrees to any other wires to help cut down on induced noise. Wire tie it in place...

it''s most likely a bad wiring connection, or one that's shorting out to ground behind the radio.. otherwise it's a bad head unit.

So I suppose all I can do is remove the HU and check all connections to make sure they're secure. It would make sense if it was just a loose connnection as the problem hasnt' been AS bad lately, but I know it's still there (comes and goes sorta). Guess I should take the 10 minutes to remove the unit and see whats up heh.

yessir
