[QUOTE="wew lad, post: 8386937, member: 665412"] your fuse is supposed to protect your wire, not your amp. Only time you use the wire fuse or distro block fuse for your amp is if it doesn't have an internal fuse (I guess you could match it with the internal fuse...) the amperage draw isn't as easy as 60a for 1200w, x amperage for y wattage. the instantaneous amplifier voltage, efficiency, and a whole slew of other factors are going to change it for every situation. The powerbass 1k amp I'm running popped 100amp fuses like cake until I upped them to 150a. I set my wiring so that it's the lowest fuse I can use that will protect the wire and still provide sufficient power for my amps, competition fusing is obviously different. Ideally you should use a fuse that is just under the limit of a wires capacity, i.e. 300amp fuse for 0 gauge OFC rated at 350amps. Keep in mind fuses add resistance and with that voltage drop and substantial heat. There's a reason why cheap fuse holders will melt. oh yeah, fuses don't blow at their rating either, they blow above it. Ever seen people burp thousands of watts on a 150a or smaller fuse? [/QUOTE]
