I have a jvc cd changer that uses the fm modulator. I installed it in my truck today. I had the unit in my Mustang. When driving down the road there is a high pitch background noise with the cd changer only. It varies with the rpm's. I know it is interference from the alternator. My Mustang had only an 80 amp. I think the truck is a lot more. Has anyone experience this sort of problem. Is there a solution?

Thanks!

 

Hi montu and welcome to FTE

If you dont get any replies here that help you might want to scroll further down on the main forum page and ask again in the Audio and Video forum. The guys there should be able to help

 

The single most important thing to consider when wiring audio components is the ground. Make sure you CD player has a solid ground. By that I mean it must be making good contact with bare metal that makes contact with the vehicle chasis. Also ensure that it has it's own ground - don't share a ground point with other items.

 

I think the ground problem may be the issue. I could not find metal (not suprising) behind the radio so I used one of the ground wires. I will try this and check the other forum. Thanks!
