    Re: which fuse and size wire do i need for this amp setup?

    good rule of thumb on fuses is every 100 watts of power is equivalent to 10 amps of a fuse. example, 1000 watts would require AT LEAST a 100 amp fuse, 500 watts would require AT LEAST a 50 amp fuse and so on. when it comes to the size wire, with that setup, 4 gauge will be just fine. you may want to think about a different amp for those subs though bro. not tryin to hate on your equipment but that amp wont do too much although it will do the job so its up to you really.
