I put a 7 light bar on my tower.Wired it up with two 40amp relays..I grounded the lights to the light bar and and then grounded the bar to the batery.When I turn my radio on a terrible squeal comes from the speakers.The only way to make it stop is to unground the lights from the battery.The lights are wired for power directly from the battery.Did I ground it right or something im missing.The lights work fine.I just cant play the radio right now....Do I need to ground each light seperatly?Please I need help becuase I unhooked them until I figure out the problem.

they make insulators for this problem, also, make sure all your stereo wires cross the light wires at a 90 degree angle, or don't go near them at all

My radio gets staticky if the engine is running.

i think the insulator just goes inline with the wire, and filters out the electrical noise, but i'm not sure, grant (whitechocolate) would know alot more about this than i do
