ChevyBoy95 Posted May 7, 2016 Report Share Posted May 7, 2016 250a or 300a fuse will be fine for 1/0 OFC.

Broke_Audio_Addict Posted May 7, 2016 Report Share Posted May 7, 2016 No reason to fuse it higher than what the alt can put out, I'd use a 150 amp fuse. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

RageQuitForLife Posted May 7, 2016 Author Report Share Posted May 7, 2016 ugh, so many different answers i dont know which one is the most correct. one of you says 250-300 and one says 150... Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted May 7, 2016 Report Share Posted May 7, 2016 If you fuse to high you defeat the whole purpose of having a fuse....

RageQuitForLife Posted May 7, 2016 Author Report Share Posted May 7, 2016 ok that makes sense. im also looking at buying a crescendo s1500.1 for my subs, but i dont know which specs i need to look at to calculate the fuse that i would need. is it the volts x amperes = watts to figure out the fuse size?
