  • Radio Interference caused by Amp

    This problem has plagued me since I put my system in, and just this morning (the morning after I put my new Kenwood in) I discovered it was the amp causing this high pitched annoying intereference on my favorite AM radio talk show. It gets worse as the amp got warmer, and go away if I turn off the system for a minute or so and turn it back on, but it comes back faster each time.

    Is there a way to cure this? Or should I just put an inline toggle switch on the remote wire?

    Thnks!

    Ask around at your local shops about this, and see if a ground loop isolater might help. Also, see if they have antennae filters.

    Oh yeah, and try sanding down your main ground point under your hood. Sometimes they don't sand it good and there's still paint on the ground point. The reason is that many a noise problem involves grounding. Check your amplifier's ground point too.

      It might not be your amp causing the "high" pitch noise. It might be your altenator whinning through your system. Take your car to a car audio shop and let them hear and or trouble shoot it, you might need an LOC (line out convertor)to filter the noise. And yes, if you don't have proper ground things will go wrong.

        It is my amp because it only does it as the amp warms up, and if I unplug the remote wire to the amp, it disappears instantly. I'm probably just gonna wire up an inline switch. The ground is superb, and I made tripple sure it was when I was installing it. Thanks for the help, guys!

          rca cables can also pick up the noise. Unplug the rca cables and see if it goes away. IF it does buy better rca cables.

          If you have a good ground then this is probably where the noise is being picked up.

            AHHH!! I didn't think of that! I got a cheap crappy RCA, so when the now 2 feet of snow melts, I"ll have to do that.

            It'll be August before all this sh*t melts
