Noise when from head unit.

[tpalik3360]

Need a little help. Been a few years since I have gotten back into car audio. The issue I am having is after upgrading my rear speakers, I am getting a small thumping like noise when ever I change the volume on my head unit or selecting an option on the head unit. I ran new wire from the rear speakers to the head unit due to having a factory premium system. I did the same thing for the front. The wires are not near the power nor ground cables. Before I added the rear speakers, the front sounded find and their was no feedback. Please not, I am not getting feedback from the motor or anything like that, just the small thumping noise when ever using different functions on the head unit or changing the volume. The ground it good on the head unit. My current set up is a pioneer avh-x4800bs and some basic pioneer front and rear speakers.

Might be a issue with the head unit or bad wiring on the speakers. Either way just unhook them. Rear speakers don't belong in stereo.

Thanks for the feed back. I ended up just taking them out and adjusting the settings on the unit and it made it sound like it should. Couldnt believe how horrible those pioneers sounded mixed in with my JL components up front. Sorry for the type o. Didnt mean to say had them up front. Just pissy because the way it sounded.
