So when I plug something into my cigerette lighter like my sirius sat. or my portable DVD player, I get bad eng. noise. Someone mentioned that it may be because of the power supply from the cigerette lighter.... any truth that and if so, what can I do to fix that?

You can hear the changes in gears. It's like a winding noise and then it stays constant once you stay at a steady speed.

Should I connect the cig. lighter to the power supply going into the head unit? Maybe that has a better filter on it. I'm thinking that the cig. lighter may come straight from the fuse box.

Did someone mess with it at any point? Because usually you only get the engine noise when you put a new HU.
