There no sound coming suddenly the amp and all buttons are working fine power as well only no sound

sounds like the motor has failed. the click is a relay that is closing. parts are here: http://www.alliedappliance.com.au/scripts/part_search.php?view=&search=smeg%20p591&ct=1#target

your needle has worn down, or the RCA leads(red & white) arn't plugged in to the phono socket on the amp,or you haven't selected phono on the source select,or you have the tape monitor button switched on.

sounds like you may need an alternator... theres not a short< your just losing battery power and the steering wheel being hard to turn is probably your engine cutting out... also it could be a seized up pully or a/c compressor...

try a different source. if there is output on all speakers in test mode, then the amps are good but the source or source switching may have a problem.

1 either ur VGA card is corrupted or
2 RAM is corrupted
3 Last may be your motherboard is gone - not sure

If it went out with no indications of trouble it's probably a fuse in the output circuit. It might be an out put amp but typically they let you know they're going bad with a little noise.

Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?

mine did that. i cleand the battery wires and hook ups now it works fine.

my amp says Lo on the digital circle on top of the amp i have a mtx 9500 bridged to the amp and it cuts out at high volumes and suddenly please help
