whatever you do, DON'T JUST PUT IN A BIGGER FUSE!! If it was running just fine before and you didn't add anything that would require more current, then all you would be doing is making your system more vulnerable to countless problems, including electrical fires.
A short could be exposed wire, could be a few strands from your positive grounding out...
Also alot of older and some new high end amps don't have thermal/short circuit protection, like old school competition models with unregulated power supplies. If your amps have fuses and they aren't blowing, then it's most likely something in the wiring, not that your positive wire is touching the negative on the amp, that would kill all the fuses on the amp and possibly kill the amp.
As someone mentioned before, unhook all the devices drawing current off that power wire, ie. amps, equalizers, line drivers... If the fuse doesn't blow when everything is unhooked try hooking them up seperately one by one, and see if there is one thing that is tripping the fuse. If it is one thing, it's most likely damaged and needs to be repaired.
One last thing that comes to mind at the moment and seems very possible is that if you had it running while hooking up the speaker wires and they accidentally touched somewhere, you will blow up any amp that does not have short-circuit protection instantly. But then the amp fuses should be blowing and not the in-line... well I dont' know try unhooking everything and doing it step by step as listed in the above paragraph. Post it up on here, someone knowledgeable is sure to help

Just because there is no obvious visual flaws inside your amp doesn't mean that it isn't blown. When you blow up the caps inside the amp they will just puff up and the amp won't run. I'd have your amp taken in to get a repair estimate if you even think the amp is worth it. But your amp is definitely the problem, i'd say #1 possibility is that your speaker wires touched when the amp was on...
