What Size Fuse For Big 3?


Recommended Posts

for alternator ied go a lil over the amp rateing of the alternator, if its peak is 105 ied do 150, if its 150 ied do 200, just to be safe, any less than the amprage might harm the fuse tryin to push more current threw it, on my trucks big 3 in 0guage i got a 150amp fuse on alternator that doe s70amps, 250 to rear wire(was to a battery but i took it out when i took out my system), in my geo's big 3 in 4guage i got a 80amp fuse on the 75amp alternator, and i forgot the fuseing on the wire goin to the back but its 4guage also, and i have no probs yet so i guess it works fine

here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp

here's a link to my other system my 90 geo prizm test car

Ok i plan on just getting a 150 amp anl for stocker. Then when i get my 275 amp dc alt in ill swap it with a 300 amp anl. Depending on whether or not my voltage stays up around 14.** ill get a mla module and run it at 15.3 im guessing with the sundown 2000d and a crunch 1400 4 channel that upgraded alt will run the system just fine. When i can ill get a few kinetics also a 1400 upfront and undecided for rear batts. I hope to see 3000 rms at 1 ohm out of the sundown :) when done. Is that too much to hope for?

you wanna fuse the wire as big as the amp rating is on the alt. my 200 alt amp has a 200 amp fuse

Ok sense i have a 105 amp alt use a 100 amp fuse? I dont think it matters but im running 2 200 amp anls for the amplifiers...

out of that one amp don't know if thats entirely possible but i do know with the right charging system anything is possible as i'm pulling around 3200 rms on full draw with stock alt big three upgrade 2 optima yellow tops and a 750cca lead acid up front and can play the system full out for about 30min to an hour before i see a huge voltage drop then again i have no power options on the car at all don't know if that matters.

thats good to know about the alt putting out more then spec. I still want a ho alt though. I have plans of upgrading every year. 4 level 4 15's on 2 sundown 2000d's should be loud ehhh? lol. Hopefully it works out. For now just a 15 is better then none.
