Had power serge from wall socket,melted wall socket. when i turned my amp back on it came on,but volume very low and muffled. i tried to reset circut breaker on back of amp,won,t reset. plays fair if yousins headphones,but not if you try to youse speakers only. there are set buttions in the rear you use a pencil ,to push inset buttons ,for bridge,or sterio if you hold the button halfway the speakers sound great,let it go and the amp,goes back to the same low muffled sound. did i blowout my amp'or what?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
Then you have found your problem. It's internal on the amp. Protection circuitry issue. Have it Benched at a shop with the same impedance you are running it at. If it benches ok, check your ground, it should be no longer than 18" and go directly to the floor frame, not a seat bolt. You should also be running at least 4ga power as well. Hope this helps.
I have a Carver amp which developed a "hum" also. As a troubleshooting step only (long term this is NOT a solution) you can use a ground plug adapter that removes the ground lug from the unit. This is an adapter that has THREE (Line, Neutral, Ground) female sockets for the amp to be plugged into, and TWO male plugs to go into a wall socket. If the buzz goes away, you've got a leaky capacitor in the Power Supply section of the amp. It will take some doing to actually fix the problem, but this will narrow down the cause.
How loud? Or how high on the volume? Any amp can produce a heck of a lot of dirty power (well above its 'clean' rated power) if pushed hard enough. Distortion will rise rapidly and speaker-killing clipping can occur. It's trying to tell you to back off.
I'm not quite sure of how the two amps are interacting here, so I'd like to request that you describe the entire hookup. Sending a higher signal from the mixer should not be a problem, but something is wrong in the setup (I think).
Please update this with a description of how you have the mixer and amps connected to the speakers.
i had the same ploblem with my amp then i found out i didnt have a good enough ground. Make sure you groung it to your weel well or some part of the frame. Or you mite be running with a fuse thats pushing to much power i use a 100a fuse 5 gage power cord to power my 1200w xplode and my 2 12" kicker comps. Or if your using two diff kind of subs then you amp is confused in why your asking for 500w on one side and 600w on the other this will also make your amp light come on.
The amp is rated at 120wpc on various websites but I suspect that number is too high since the amp weighs only 15lbs. The 400 watt spec is power consumed - not speaker/RMS power.
As for blowing out your speakers, that far more likely to happen with a low powered or cheap amplifier like the GLI A-6300. A low powered amp will quickly burn out a speaker if driven too hard. If you want to protect your speakers from damage, either keep the volume at a reasonable level or buy a bigger amp.
When I turn on my marshall amplifier its makes this unusual, anoying sound. it sounds like a small motor or a fan going. the sound of the amp is good but its just makes this motor sound when I switch it on. can you help me find the problem.
