Fuse help needed

[vawakemonster]

While driving downtown my speakers all went out. when I arived at my girlfriends I discovered the fuse ahd blown in my phoenix gold amp(25 amp fuse.)

each time it ried to replace it the fuse would arc or blow the second it touched or was inserted in the amp. I tried to take hte fuse out of my power line and put it in my amp btu the amp fuse blew the second the fuse was plaved back in the battery line.

I unplugged the speakers and the amp still blows a fuse. What should i do?

So the fuse on your power wire is fine but the fuse on the amp keeps blowing? What size fuse do you have on the main power wire?

Bad amp? Shorted transistor?

no, what's happening is he unplugged the larger fuse on his main battery line, put the 25 amp back in the amplifier, then replaced the big one and the 25 popped again.

... 25 will blow first because it's smaller.

IF -- IF -- the amplifier is blowing fuses while it is turned off, then it is likely that the power supply is shot (or the output is shot and it caused the power supply to go - more likely). IF it blows fuses ONLY when turned on, then the output stage is likely only blown.

Either way, you're looking at a rebuild, which isn't cheap.

... good -- 'cheap as free' is always a positive.
