New to posting but have used this forum for other problems I had. Ok I have 07 jeep jku. Stock radio with sunpie led headlights with halo rings. Here's the problem ... if I have the aux cord plugging in with nothing attached and the radio on its all good.... as soon as I turn the headlights on I get a high pitched noise through the speakers. The noise doea not change with rpm. If I disconnect the aux cord the noise stops or if I leave the aux cord connected and turn the headlights off the noise stops. It only happens when both are on and plugged in. WTH !!! Hope someone has had this issue as it drives me crazy. Also can't remember if it happened with the stock headlights. Thanks in advance for any suggestions. Just installed big 3 to see if it helped and it didnt but it did up my voltage
