I think its somthing to do with your wiring, somthing about a common ground between the both. i had a simular problem in my old car, when i turned on the lights it cut out the sound.

sounds like you may have the phono leads and the power leads running together
its always best to run them away from each other as they can cause interference
like you have mentiond
keep your phono leads away from any other power supplying wires like wires to your lights

im almst 100% sure this is the problem

hence – no power to your lights and no noise send power to run your lights and you get interference

good luck

That’s weird man. I don’t understand how the headlights can affect the amplifier. Did you check the RCA inputs to make sure that they’re isolated well. Where did you run these RCA wires?

If the car is running without lights on there is no noise, only if my parking or headlights are on…thanks for the quick reply!

Alex,

Does this happen when you turn your car lights on? Or just when you start your car? If the humming sound happens only when you start your engine, it maybe related to the RCA input to your amplifier.

I just installed 2 10″ subs and a 2000 watt amp in my 325is and have after market LED tail lights and whenever i turn on the lights of my car i get this crazy obnoxious hum from the speakers, any suggestions on how to get rid of this?

Do you still have those two connectors for the amp? I could use them.

Thanks,
