Ok I currently have the amp grounded on the left-hand side factory ground point in where you go to change the bulbs ect. I get noise on my sub occasionally, and it pop's when I turn on head unit and when I turn it off. Could this be the ground I am using?

If it is then were would you lads suggest I ground the amp to?

Thanks Linch

Try grounding it off of one of the seatbelt mounts. They are a bit more substantial.

They tested the amp itself?

How?

Did they use the current earthing point? If so, that could still be the problem.

yes a sub popping is a bad earth. Get it sorted ASAP before you amp goes awol and fuks your sub.

i tend to earth with a thicker AWG than my live, also your earth MUST be shorter than the live wires.

you can test a sub your self by measuring the resistance between the two terminals. if its infinite, the coils have gone. i dont know how to test an amp your self thou...
