My fuse in between my batterie and amp on 4 gauge wire keeps blowing up can I juste put a bigger fuse 30amp to 80amp?

My fuse in between my batterie and amp on 4 gauge wire keeps blowing up can I juste put a bigger fuse 30amp to 80amp fuse in between my batterie and amplifier on 4 gauge wire keeps blowing up could it be a short, bad ground or my amplifier is to big for the fuse cause I blew 2 30 amp fuse in less than 2 minutes each could I put a 80amp fuse on my 4 gauge wire Asked by newuser9494189 43 months ago Similar questions: fuse batterie amp gauge wire blowing juste put bigger 30amp 80amp Consumer Electronics.

Hmmm. It's not the wire that's the determiner of the fuse size, it's whatever it's feeding. Look up the specs on your amplifier, use the recommended fuse size.

If they don't mention a recommended fuse size, use one that's about twice as large as the largest expected current drain. If the fuse blows anyway, you may have a short to ground or to other wires on the amplifier's output. Or a short inside the amplifier.

If the amp gets hot with no signal, there's a problem in there.

There's a reason why the fuse is there Sure, you could replace the 30 with an 80, but it's not real smart. Whoever built the system knew that there were components that would fry if they had too much current. They used the 30amp fuse as a way of protecting things.

Fuses are not evil - they are there to protect electronics and stop fires fro m starting. The fact that you blew 2 30s in 2 minutes means that you have a short somewhere, or you're pushing too much juice through. If that's the case, there's no guarantee than an 80 isn't going to blow too.My guess is that you're not grounding properly and you're sending too much current to the amp.

I'd get that addressed first or you'll be replacing fuses forever.

Check the ratings on your amplifier(s) your fuse should not exceed the rating on the amplifier. (if you have multiple amplifiers, each one should have its own fuse. ) a bad ground won't blow a fuse, but a short is a definite possibility.

If you look closely at your wire, there will be a temperature rating printed somewhere on it. If it's 60C, you can go up to 70A fusing, 75C can use 85A and 90C can use 95A (this is the total of all fuses on the wire) .

I believe it depends upon the rating of your amp. If it is labeled as drawing more than 30 amps, you would probably be safe putting in a fuse up to the rating. Beyond that, you risk blowing the power circuit inside the amp.

Something much more difficult to fix than a blown fuse. If there is a short before the amp, the fuse will probably still blow. You might try a direct connection and watch to see where the fire starts..

1 According to the wire tables, 4 gauge should be able to handle 80 amperes. 80 amps is a big load on a battery.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
