I'm adding a couple amps to my 2005 Chevy Blazer. I'm using a couple line output converters to drive the amps. Everything works fine during the day. At night when the lights come on (dash lights, and dim's the raido's display), i get a hum through the system. Sometimes this is worse than others.

I have the ground wire from the LOC's grounded to the same ground line as is going to the stock radio.

Any thoughts on this?

try putting one of the ground wires on the metal of the radio and the other ground to metal on the car.

I've never used the ground wire on an loc. Try disconnecting it first, then reground the headunit if needed.
