Fuse size

Yeah some people....need to learn to shutup and respect others' threads. But that's wishful thinking.

I apologize in advance if anything I did....but felt I did help ya in any way I could.

Tried over at SMD....turns out if your not buddy buddy with people there, one person gangs up on ya....then he has his followers. That's NOT a forum.

All of this really helped me decide what size fuses to go with

You got your answer early

Doesn't wire length effect current handling or no? I have 1/0 cadence CCA and I'm running about 10 feet for power wire for a skar rp2000. The fuse rating on the amp is 200 idk if I should use a 200 fuse or something a tad bigger like 250 to avoid blowing fuses

Yeah once it gets over 20 feet it starts dropping but 20 feet is a very long run. And no amp is pulling that much current all the time.

I gave you a nec list of fusing for the wire.

Sure did with 5 different answers. 300,350,250.(2) x 175. I already know what's up just find it amusing how this thread took off in the wrong direction. Maybe Kuthe should give some help here too //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I gave you tge national electrical code guidelines which is down to a science there is an answer a correct answer it's on that link I gave you

Isn't that chart for AC? You know we use DC right?

Btw. Have you figured out what sound quality means yet? I see you haven't returned to Diyma.. or do you think you know more then all of them also?

I have a life. No one is capible of a techinal discussion.

I told you. Sound quatitly is accurate reproduction. Alot of factors are involved.

Dc does t matter. Its about the current carring capibilities with reguards to voltage loss and temature of the conductor.

Ok in your own words what does accurate reproduction entail?

How about this. What is stereo, and how does it work?

Btw. My chart is better then yours

1/0 ofc wire for car audio use have been standard 300A fuse per run for as long as i can remember.

do not split the fuses.

fuse each run at 300 amps.

If something goes wrong with your amp the fuse will keep current flowing long after your amp has destroyed itself.

It is there to protect the wire.

fuse 18" from your front battery on the front to back run, 18" from your rear battery on the front to back run, and 18" from rear battery to amp. (many people do not fuse from rear battery to amp as it is generally a short run only a couple feet long with few obstructions to damage the wire)

If you want to be extra safe fuse from alt to front battery.

This isnt rocket science...

stick to 300a per run and you will have no issues

You a *******. Thats NEC code. Lol

Not even close. Ive provided the charts and you can research fusing. You can use dual 300s but each wire is only going to pull half of the current of the load.

The nec list is not a guess its been tested for over 50 years. Part of my job is to test tempature of the conductors to make sure over current is avoided.

If its not in the NEC code book its bullshit.
