You are fusing for the wire not the amp....
The amp already has its own fuse. You are fusing the power cable in the event the power cable might get a slit in it and short itself out to the car body which will quickly turn into a fire. Fuse as close to the power source as possible as the length of cable before it is still unprotected. From http://www.bcae1.com/ Wire Gauge Recommended Maximum Fuse Size 00 awg 400 amps 0 awg 325 amps 1 awg 250 amps 2 awg 200 amps 4 awg 125 amps 6 awg 80 amps 8 awg 50 amps 10 awg 30 amps 12 awg 20 amps 14 awg 15 amps 16 awg 7.5 amps These are the recommended maximum fuse ratings for the corresponding wire size. Using a smaller fuse than what's recommended here will be perfectly safe. |
