Well, using all my genious I accidently hooked up the 12v wire to the ground terminal and vise versa...and blew all three fuses in the amp....F*CK!

My question is,

what is the possibility of my amp being completely buggered?

Can I just replace the fuses and be on my merry way?

did you replace the fuse you have inline with the 12v from the battery?

my housemate wired his 1000watt alpine monoblock backwards and blew all the fuses but it was okay..

i think that is why there are fuses ther to blow and stop any damage to your piece of equipment

I instantly checked that fuse (if your referring to the one that runs along the power lead?) and it's not blown.

Just the three external fuses on the amp are blown.

Have you replaced them yet?
I'm guessing you havn't because you havn't got any spare. Open up the fuse box on your dash and pinch 3 irrelevant ones from there to use quickly for testing purposes. Or wait till tomorrow and you get to the shops. (and probably take this as a lesson to keep spare fuses)
Since the fuses are blown I doubt there's any damage, as the fuses blew so there wouldn't of been power going through it (or only for a very short period of time).

buy a bloody multimeter and check that you have 12vdc at the terminals before you connect them to your amp. if there is no 12vdc then there is another fuse blown further back. It has been said already, but that is the purpose of fuses, as they will blow to protect your equipment from damage. Modern amps generally also have some form of reverse polarity protection. And just one more thing to remember while you are at it, always replace your fuses with the same amp rating or you will damage your system.

reverse polarity on car gear usually wont do any damage apart from blown fuses as most gear would have diode shunts on the DC supply input to protect against this kind of thing... unless its a s**t design. Reverse polarity on the remote sensor line will probably damage the amp though. Never seen a protected remote input on an amp yet.
