Fixing amp or just get sell the stuff

[cojo]

ok well the amp worked for a lil bit then stopped, I then turned down the gain and bass boost and changed some other settings then it started working. I then when working on my car noticed the fuse by the battery, that the end had melted so I pried it out and put a new one in, it continued too work... Then the other day it turned on and went out, I noticed today that the new fuse I put in was burnt...

So I think I need a bigger fuse block made for bigger amps... right??
any suggestions?
