1) Make sure the amp is properly connected to +12V power source. 2) Make sure the amp is grounded well, directly to metal - if you have a voltmeter, an easy way to check the first two is to see if there are 12 volts across the power and ground wires. 3) Make sure the speaker output wires aren't touching each other. If none of these are the case, there is an internal problem with the amp and it should be serviced or replaced.

    Also, what ohm load are you giving the amp? How do you have your speakers/subs wired up?

Can anyone help

What size is the amp and how many watts is the speaker(s) you have it ran too? If your speakers are trying to pull too much power from the amp it will turn itself into protect mode to keep from blowing a fuse as well as if you are pushing to many watts into small small speakers it will do the same to protect from blowing the speakers I would recommend turning the settings on the amp down slightly and then trying it out also make sure your wires arnt crossed adjusting the setting as it plays is the easiest way to fix the problem also make sure the bass isn't all the way up on your head unit

Amp on but no sound

Double check all of your fuses and make sure they are the corrects AMP. Other than that it sounds like the speaker wires came loose somewhere along the line. check on the subs and behind the deck. hope this helps

My Pyramid Arctic Amp 1000 watt was working fine for about a month then one day the protective light came on and stayed on as long as the amp had power. So now it wont give any watts to my two 12's....

Troubleshoot to the component level to find out what is causing protect mode. A short in the output stages as a result of overdriving is one likely suspect.

My boss amp is on protection mode and it wont work its a 3500 watt chaos idk what is wrong with it

Likely one of the power amps has failed component(s) and does not achieve electrical balance which then goes to protect mode to prevent damaging your speakers.

You will need to have it serviced.

JVC 600 watt amp overheated

Yes it has a protection mode, let it cool for while then try it again, if it over heats quick make sure you're not running the amp below its stable impedance.

Amp goes into protect mode after volume is turned up

Not enough juice, check the power and ground connections, another possibility is to have dc in the input, try to use in line filter available from radio shack to cut the dc, also test the with one speaker at the time, you could have a bad speaker (shorted) too.

Thumping speakers - no power light is on - wired correctly

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.
