My friend has a 1200 watt Boss amp (dont laugh) pushing 2 10" sony xplod's. he had a 30A Fuse in the amp, and it popped. so he put a 40A fuse in, and the little plastice around where the fuse goes, is melting. the fuse under the hood also gets very hot, and burnt up the holder for it. any help would be greatly appreciated. wmosher3@tampabay.rr.com

If it is really 1200 watts, it is drawing around 100 amps, i assume if you are using a 30A fuse you are also using like 8 gauge wire...? Too much current draw, use the correct fuse sizes and wire sizes (if they are incorrect)

a few things...

your power wire may not be big enough (get a bigger guage)

your ground may not be connected well enough (try relocating it)

1200 watts....that is a lot of power, put the same size fuse in the amp as it came with...then make sure the fuse under the hood is about 10amps bigger

It conclusions,,,,use what size fuse and power wire Boss recommends you use for that amp,,,going smaller will give such problems

You might also be over loading your amp...so check what Boss says your amp can be run at and make sure the total sub impencance is not lower than that

well having a wire larger than needed will never hurt so if the amp really puts out 1200 watts you are looking at 2-4 gauge, i would recommend 2 gauge, with maybe 100 A fuses, that should be fine since that 1200 watt rating is most likely peak

well, it is a BOSS amplifier. so it is probably putting out 600 watts at the most, even though it is a 1200 watt. i dont think he wants to run 2 gauge wire (for now anyways) what size fuse should he put in the 8 gauge? and in the amplifier?

The amplifier fuse you should go back to running with a 30 if that is what it orginally came with. Putting a larger fuse into the amp is going to leave you with little to no protection. You will probably want around a 60amp fuse on an 8 gauge install.
