i installed a set of H.I.D head lights and when they're on i get a lot of static through the radio. it only happens when listening to the radio like its not getting good signal. as soon as i shut off the lights the static goes away. i have done the mod with RCA plugs sliced into the tape deck and when i use my tape deck to listen to music there's no static. i really don't know whats wrong with it cause my friend hooked his up the same way i did (same kit different bulb size) and he don't get any static. i hooked the power to the battery along with the negative to the negative battery cable just like he did so i don't know. please help.
