buzzing noise

I have recently installed a 4 channel mtx amp for my inside speakers, since I have dont that i am getting a buzzing noise coming from all the speakers, i pulled out both left and right rca from the amp and still getting the buzzing noise, I also moved the location of the my ground for the amp, and still getting the same buzzing noise, any ideas what could be causing the buzzing noise and how can I get rid of the noise, when I turn off the amp the buzzing noise is gone.

Do you have a Pioneer radio?  Do you have an ohm meter?

move your rca wires to one side by there self and have your power and remote wire on the other side by their self but don't forget to redo your ground overboxead78

I have clarion pop out deck, and I have a bmw so the battery is in the back of the car, i only have the the three rca cables and the power wire coming down together on the same side, do you think it would be the power wire causing this problem

2 Questions above.  And one more to follow, does the buzz change when the engine RPM is increased?

O sorry no I dont have a ohm meter, and when I do drive you can hear a increase in the sound

and its a clarion pop out deck

I was just outside in my car, and i did not start the car, i just turn the key to play the music, and there was no buzzing noise, but once i started it the buzzing noise came, I then ran a stight ground from the amp to the battery, and the buzzing noise got louder.

when i pull out both rca from the amp the buzzing noise is still there
