Make sure your ground on your radio is good...

Verify ground is good to head unit. If that doesn't help, ground the LOC. If it doesn't have a ground tap, get one that does.

Also make sure your amplifier grounds are very, very good... not screwed to sheet metal with sheet metal screws and not under seat bolts sitting on carpet. You need a solid ground with the paint scraped clean. Shock towers work well.

Thanks for the fast response ! Will check my grounds from my head unit this weekend also will post some pictures of my amp grounds tonight since im prettu sure they are well grounded , i sanded them and drill a hole on the frame and rear shelf of my trunk ! I also bought yesterday a pac ground loop isolator yesterday from sonic elelctronix which had good reviews

Ground loop isolators don't fix ground problems, they mask them. Be sure you exhaust all other possibilities before using an isolation transformer.
