what would cause the fuse to melt on a amp?
Its running fine but yesterday it stopped and I found the fuse to have completly melted. Had to be pulled apart with needle nose plyers. Put in new fuse and it still works thank god. [img]graemlins/dunno.gif[/img]

using a fuse that is rated for more amps than the amp specs say is just about the worst thing you could do. if it melted the plastic, then there could be a number of possibilites.
go get it looked at. using a fuse rated higher than the specs say, is no worse than taking a paper clip and bridging the contact points.
sounds like a short though, even if you had a lower rated fuse in there than the specs called for, it would just pop the fuse under heavy load, not melt it...

the amp uses a MAXI fuse of 30A
both the fuse and the plastic around the connections points melted something awful
I had to dig away the remains to get enough room to put in a new fuse
what would cause this problem?

As for the fuse - I've seen this a few times and the only loose common denominator I have found is a system with fairly high power on a light duty charging system and usually a regulated amp. Battery voltage drops so current goes up and this fools the fuse so the element does not melt but it gets hot enough that everything around it does. Dunno if that is 100% correct but that's my theory.

having worked in service i know exactly what cause this. your voltage dropped...alot. and it compensated by spiking your wattage. it might hapen again but your best bet is to check your connects(make sure they are not corroded or loose) make sure that your battery is good(no weak batteries and all conenctions are good) and then your alternator(make sure its good and that your connections are good)
see a common denominator. make sure all your wiring is good and not loose. checkit at teh ground point all ove the car engine and amp. check all the power and remote.10bucks says you got a loose connection at the amp.
last thing. were you listening it full boar with the car off? thats a no no. that will draw tones of power and make your battery go from 14 volts to 10 and shoot your current up. id probably say that a loose connection is what did you in. or a corroded connection. you are in edmonton and there is always tonnes of corrosion in alberta cars.
good luck and keep us posted as to your findings. 10 bucks says that dukk probably has never seen this problem and other guys like tim and stuff cause they install properly and never had issues with electrical like this. although they may have seen it on cars that other people install.

corrosion on alberta cars? no salt is put on the roads
I have another amplifer in the car and it isn't doing the same thing although I will double check the fuse condition on that one
on Thursday I was waiting in line for a car wash with the car off and listening to the music at half volume
car battery is a Optima red top, alternator runs good, only about 6 months old
I'll take a long look at the wiring to see if anything is loose or corroded
