1. check your grounding. most likely bad grounding that causes this.
2. if you have an external amp. check the gain level and adjust it down until you cant hear any humming.

Hello, thanks for the reply. Ok sounds like a good plan, but this may sound a it blonde but which earth do i check? behind stereo or in the engine bay???? also i do not have an amp.

Thanks!

The one to the stereo.

Theres also a good idea to ground the engine better also, as the stock grounding is pretty bad.

could be the power wire you used.

This is caused by a ground loop



What is a ground loop?

np. People are always asking why their radios are humming on siriusbackstage.com and I just bookmarked that link to give them

on a side note you can also pick up a ground loop isolator at the following places:


USA: Radioshack


Canada: The Source
