what brand circuit breake to buy??? and amps ???

Wouldnt touch one. Way to many moving parts for it to fail in the environment it would be in. If you do some more searching you will find some car fires caused by them.

You use circuit breakers in your house don't you? If they are high enough quality for houses then why are they not good enough for car audio purposes?

apparently you missed the whole first part of that post...the environment of a car is completely different than that of a house. the car is in motion, hitting bumps in the road and shifting things around internally. now, add in some subs on top of that and you are having some serious vibrations. do you have those same things in your house?

fuse holders will not come loose from vibrations, but the components of a circuit breaker which aren't designed to take that kind of abuse will.

Good try. Its not the same type of circuit, same quality, or even same standards.

this is the brand I'm running. Circuit Breaker, 120 AMP, Waterproof [(N-11) CB-120] - $30.00 : DC Power, We know how to make connections!

Your popping it cause its not a big enough one. Run a size breaker that's matched with your wire rating sorry if that was said didn't read through.

ok so need maybe a 200amp breaker and or fuse running 0 gauge wire

Most 0 gauge wire is rated at at least 250 amps.

I've heard that the more you blow a circuit breaker the less current is able to pass through it before blowing it again. Just a thought.

no nothing wrong with my setup just wondering what amperage breaker or fuse to run on my set-up i was thinking 150 amp to small for a 1500 watt and a 400 watt amp ??

im running 150 amps of fusing up front for 2k+ daily and over 4k on burps. ive never blown or even discolored a fuse. so something isnt right.

That's because you have a battery bank in the rear, most of your current is being drawn from that.

Punctuate much?

nope!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! haha

i replied this answer few posts back. the fuse is meant to protect you from drawing too many amps through the wire, and starting a fire.

fusing too small is not dangerous, fusing too big is. so the way it done is fuse to the MAX safe amperage of you gauge of wire. 0 gauge is 250 amps.

and 150 amps is not too small. but its irrelevant, we need your wire gauge size to determine the APPROPRIATE size fuse.

You have to be careful making a blanket statement like that, I understand it's correct a lot of the time but not all of the time. A lot of larger amplifiers don't have internal fuses so they require you to fuse the power input line. If you have 1/0 and fuse according to the wire (~300A for good wire) but your amp calls for a 200A fuse, well then you could have a problem where the amplifier gets way too much current but the wire is still fine.

So basically, you fuse for the wire so long as your amplifier has it's own fusing, if it doesn't then you fuse for whatever the smaller value is (recommended amp fuse size or wire fuse size, but ideally the wire fuse size should be larger)

Yes, but most amps do. And most people who would have an amp that does that much power would usually have the wire coming from a battery bank in the rear, with a single wire dedicated for that amp. And they would most likely know what they are doing. So, for the most part, I think this statement is irrelevant.
