check your grounds, make sure they are a maximum of 12", the shorter the better. Make sure you are grounded to bare metal.

If that's already taken care of, and to eliminate your problem being a grounding issue, then check the resistance of your grounds. Take a DMM and a piece of wire, run a jumper from the battery negative to one lead of the DMM, and the other on your grounds, lower the resistance the better.

hello ! the ground was checking it is perfectly ok. it seems like something else cause the noise problem when I add any small power like cross over or power amp and will cause stereo feed back I did try different locate ground but it didn't help at all .
