After just over a year of service my amp has decied to die on me.
Every now and then the music will turn off and then a few hours later it will turn on again when i come back to the car, but no it wont turn on at all. however if i hit the amo it makes a whirring noise like when its working proberly but there are no lights on anymre and still no sound. i've checked all the fuses and power wires and they seem fine. i have heard that a common problem is a blown MOSFET, but of course i have no idea what that is or how to fix it.

Any ideas, if its any help its a Audiobarn A440T or something like that!
cheers,

What? It turns off by itself? Doesn't turn on? I reckon its in the power stage since no lights turn on. Possibly a loose connection in the amp.....but yeh..audiobahn...hmmm.

seeing as though it 'fixes' temporarily when you hit it, chances are something is loose. Bad connections also cause whirring/alternator whine sounds.

Time for repair! If something electical is playing up I wouldn't risk fire damage, if not for your car, do it for your own safety.

**** just buy a new amp not like there overley expensive.not worth having your car burn to the ground

send it in to get serviced if ya really wanna save the hastle of workin it out yourself. i got one of mine serviced by geelong car sound. 80 bucks later its good as gold.
