gday guys,

I recently added a New class d Kennwood 1000 watt amp and 2 Kicker Comp 12" subs to my car,
I kept my Premium Sound ICC and simply tapped into the wires behind the glove box, and from there used a line converter which runs my rca cables back to the boot which connect to the amp. It all works fine apart from an annoying fuzzy noise when i listen to the radio? listening to my iPhone through an aux cord is fine though? any ideas why this would be? thanks!

do you think it could have anything to do with my ground wire?

most likely have a s**t earth
and are your sub/amp power wires running on the same side as your speaker wires? that can make it fuzzy
could just be s**t reception from the aerial? did you bump the aerial plug at all?
