I am usng a ripspeed R2100 Amp JMB 1000W Sub speaker the amp has 2 25amp fuses attatched, but I do not know what fuse to use in the main audio power cable, I have been upto 40 amp it blew that, I dont know if I maybe have wire something wrong, can anyone help, thanks
you always take wat amp fuses you have in the amp and add them all together and thats the minimun fuse amp you can have in your power, your amp has 2 25amp fuses so you need at least a 50amp fuse on ur power wire, and if you have the lil fuses you cant go beyond 40 so youll have to go get a MAXI fuse block and get a 60amp fuse and you will b fine, you can find them on OKorder for less than 10bucks or at walmart for 15-20bucks, good luck
G man and timothy are the only ones who are right. The others do not understand about fuses. The current rating is an absolue so an 8amp fuse will blow when 9 amps goes through it. The voltage is just an indication of the possible use, but it just does not matter in this range. At all. SO sorry your husband is right and it would work fine and give exactly the same protection as the original. You are not changing the specification in any way that matters. If you want the physics, heat produced in a wire equals I (current) squared x R (resistance) x time (seconds) Joules. No voltage element in that equation. SO if the current flowing generates more heat than can radiate away from the fuse wire, it will get hotter until it melts - when the fuse has blown.
