What Would Cause This Amp To Blow Channel 1 Fuse

[treossi]

got a free 2 channel today, i hooked it up in my car, and it just keeps blowing the channel 1 fuse, it's not a big deal, i'm over it, just wondering what would cause it to do that, and if i should even bother repairing it, it's an audiobahn 800w amp

the leds come on, but no output, then it blows and shuts off

Channel 1 fuse?

Does it blow when you just connect the power or only when you switch the amp on with the remote lead?
