I've come across a problem. Everything works fine but the AMP is ALWAYS on even when the car is off.

I've checked that the signal cable is plugged in correctly, my friend also checked it and it seems to be in properly.

I think this started happening after i had an accident... My friend believes it MIGHT be the AC wire (might be damaged or something) but we are unsure.

Any suggestions? or should i take it to a professional and let them look at it?




Also is removing the negative from the battery and removing the ground wire in my boot the same thing? and what happens if this is not removed first?

Thanks for the help =]
