Rep Power: 693

whenever i turn my HID on, an untuned sound comes from the radio channels.
can it be because of the HID high voltage or not?
and how can i fix it?

Voltage that goes into the hid transformer is less then a stock bulb. It's what comes out thats more powerful.
So that might not be your problem. Try to check your grounds first like 2 tone said. It
sounds like you have interference.
Check if the wires around your hid trans. is close to the antenna/cable(depending on your car).
You can also check if your RCA's going to you amp are close to the power supply wire. Because that will cause it for sure.
Goodluck.
