Make high pitched annoying sound go away.

Question

I just installed some new speakers into my pickup they are; a Visonic 12" sub, and two custom 10" subs with built in tweeters and midranges. It worked just fine for a while but just a couple days it started making this really annoying high pitched sound I think the sound is coming from either the tweeters and/or the midranges.

Any help would be GREATLY appreaciated.

Check your ground connections, possibly move them. You may need a ground loop isolator.
