Amplifier Fuse Causing Melt

More likely than not you don't have your speakers correctly wired to your amp. Your amp is only 2ohm stable in stereo not mono. So your speakers need to be wired one to each channel of the amp and you should have no problems with blowing your fuse.

ok, that's where im having the problem understanding it. mono meaning one of course, and stereo left and right...hmm, still kinda confused

What you need to do is wire your subs to that amp as if they were normal speakers. One sub to the left channel and one to the right. Your amp is only designed to run at 4ohms when bridged. With the way you were running your subs they were presenting the amp with a 2ohm load... hench the reason for the amp frying your fuse. So with your subs you only have one wiring option.

ok, i think i understand now. so if they were say DVC 4-ohm speakers, then i could wire each one to 2-ohms each and in stereo. and i would get the most out of the amplifier? got it thanx for the help

Yeap you've got it on the head! No probs.

try getting rid of the fuse and install a circut breaker.

yes, only 1 spot for 1 fuse
