1 F Capacitor Fuse,how many amps ? -- posted image.I have a 1F Capacitor and the manufacturer (Road Rage) does not list what value the fuse should be,is that because it depends on the amps used ?,i was wandering if just the subwoofer should get the cap boost or share it with my midwoofers as well,the sub amp will delliver 100 W x1 and the midwoofer 50 W x2,now what my confusion is how many amps should i use for the cap alone,ofcourse there will be a main fuse in line for the whole system.

1 F Capacitor Fuse,how many amps ? -- posted image.Regarding fuses;my components conssist of 4 amps,one requires 40 A and the other three need 30 A and one unit at 3 A (crossover) plus the capacitor mentioned above,what value should my main fuse should be coming from the battery,i thought a 70~80 A would do,'m i wrong ?

Thank you again !

The fuse should be determined by the size and length of the wire, and the size of the wire determined by the load you're pulling. Usually, a cap doesn't need a separate fuse - It is run inline with the power, and the wire gauge doesn't change, so the main fuse on that wire is what protects. Regarding how much power you're goign to be pulling, you didn't give us a value on all of your amplifiers. So instead of calculationg it for you, I'll refer you to here: http://www.eatel.net/~amptech/elecdisc/caraudio.htm   Click on the fuses section just down a little on the right nav bar. That'll get you started.
