    So my buddy had a garage sale today, and said i could have an amp for free because it keeps blowing fuses. I thought it might just be a misconnection in the wires or something, so i took it home and just put a new fuse in it. Connected the power wire, then right when i touch the ground fuse blows. I looked at the markings on the amp for positive, ground, remote and i tried again. Right when i plug in the ground the fuse blows, remote and rca's and speaker output are not even plugged in.. Any ideas why?

    Amp is a MTX Terminator tn250/1

    Without having it in front of me on a bench?

    No clue.

    Smell it... does it smell burned?
    Open the cover and see if anything looks burned.

    Most likely it's been overloaded and one of the output transistors is shorted, but again, no way of knowing from here.
    Beyond looking for physical damage, there's not a lot that you can do without a schematic, signal generator, and scope.

    I'm guessing faulty amplifier! The fuse is really meant to protect the wiring in your vehicle in the event the amplifier fails (or something isn't connected properly of course) but mostly to protect your vehicle from damage from the amp when it eats itself.
