hi, i have a 1990 camaro rs and i have all new speakers put in my car. i also have a fairlly good cap in my car as well but when im driving down the street and i have on my radio and my headlights i get this weird static like sounds coming out of my speakers. it works fine though with out the static if i dont have my headlights on. almost like im draining too much power from the battery. wuts wrong and how do i fix it? any help greatly appreciated.

 

Do you have an amp?

Check all your wires, check your ground, try and keep your ground as short as possible.

Just double check everything.

 

this may be a stupid question but are any speaker wires near power wires for the headlights?

 

are the lights dim when they are on? I wonder if there isn't a short in the headlight wiring somewhere

 

I get some static on certain, 92-96 FM, radio stations when I turn on my HID headlights, but, if I disconnect the drivers side HID bulb and use a standard headlight, it doesn't have static. So I know it has something to do with the drivers side HID ballast and/or bulb. I even installed a "ground isolator" on the antenna lead near the radio, doesn't help at all.
