Anyone ever have a problem with a buzzing sound from your speakers?
When I turn the radio off its stops but comes right back if I turn it on.
Usually if I shut the car down and start up again it will stop.

keep your cell phone away from your radio they can mess with them

check your ground wire behind the stereo, same problem was going on w/ my dads truck.. and that was the issue

usually a bad ground, either from your deck or even one of the amps if you have the Mach 460 system. Might be worth regrounding your deck, just find the ground wire and then reconnect it to a good clean ground.

check a few things, make sure the speaker cover is secure and not vibrating on window, this could cause a constant buzz. Or it could be altenator noise, does the buzzing change pitch when you push the gas? Or you could have blown one or two speakers.

It does change pitch when I give it gas, but it doesnt do it all the time. I can go days, weeks, months and then it will start.

the sound comes from all the speakers. And it doesnt do it all the time.

Its your ground. Take your ground off and use sand paper around where it makes contact with the metal, then wipe it with some alcohol to make sure you get it clean and reconnect. If that doesnt work, might try a ground loop isolater.

Ok, I checked the ground and there are three grounds to my radio. The antenna is grounded, there is a main ground and another I dont know what its for, but I checked and I had continuity to the chassis from all three. And the radio would power up with any one of the three but not without one. So I grounded the 2 wires to a new chassis point and left the antenna alone. But it isnt buzzing currently so I wont know if what I did will fix it. I guss if it never does it again it worked.
