Some components inside the amp will cause an output buzz when they fail. Time to take it in for service.

My line 6 spider jam buzzes in all amp models. I tried a reset with no luck. Sound almost like a blown speaker but that is not the case. All recording play perfectly.

Sound like an open ground wire on the output jack. The buzzing is usually due to this ground problem. check all wiring to the output jack.

I have a kicker impulse ix702 that keeps blowing its fuse when I turn it on.

Take a volt meter, put it on continuity, cross it between the battery and ground term. on the amp and make sure you get no buzz, now cross it with the remote term. and make sure no buzz. Make sure the only thing hooked up is the battery and ground then take a wire and cross it between the battery input and the rem. to turn it on and see if it blows. Make sure all other cables are removed.

The 3 front speakers have started to buzz. When I unplug them in moves to the rear 2 speakers. I orginally thought it was the speakers so I got new ones, same problem. Not sure if it is my reciever getting...

This is a grounding issue either between pieces of equipment or inside the receiver itself.
There are other possible causes, but this will almost always be a grounding issue.
I recommend unplugging everything and hooking it up piece by piece till the buzz return to isolate the issue.
IE - start with nothing but the receiver and speakers hooked up. Turn on the radio. If the speakers buzz, the receiver has an issue and needs to be repaired or replaced.

If there's no buzz, hook up the DVD player. If the buzz returns, there's some issue between the DVD and the receiver....
If the buzz hasn't returned, hook up the.....<insert name of next piece of equipment here>
you get the idea.

I have a Pioneer Gm-x722, and i hooked it up to 2 6x9 speakers and two 6.5" speakers and I get a buzzing sound, how to I clear up the buzzing?

try grounding the shield of the rca cables and see if the buzzing goes away. if so you have a bad ground to the rcas either in the deck or the amp. grounding the rca cable shield should take care of the problem.

Usally a ground loop isolator will fix that problem. It plugs into the RCA's between the radio and the amp.

Try to reground the amp in a different spot.

Or run a refrence ground from the deck to the amp next to the remote turn on wire. (still keep your main amp ground hooked up)

DO NOT run your power wire next to the RCA's, that will induce a field which in turn can cause that buzzing sound.

Amplifier is buzzing when i plug in my les paul but ok with other

Several things to try:
- Probably already have, but another guitar cord.
- Ground switch on the amp?
- I had an older guitar that buzzed due to the pickups. While touching the strings, all was well - I was acting as the ground then. The ground wire broke, so it buzzed no matter what. The ground wire ran to the metal bridge.
- Play louder than the buzz! :)

Buzzing from speakers

sounds like a capacitor is taking a long time to do it's job. You might want to see how much it would cost to repair.

No sound at all

The jumpers are there to connect the preamp section to the power amp section and are required for the receiver to opperate properly. Make sure the receiver is set to the proper input, in this case: CD. If there are A/B speaker connections, be sure the receiver is set to match the connectors you're using. If there is still no sound, profesional service will be required.

Speakers making loud buzzing noise

From your alternator, Make sure none of your RCA's are near a power wire, check your grounds as well.
