Have you thought of this when you externally fused your top$$ amp!!

So Im in the middle of my build, and I'm about to fuse my triple-input power/ground amp. Each 0 gauge power wire will have an inline fuse, 200A X 3= 600A total.

What IF one of those fuses blew out while playing music, but the other 2 fuse are still fine. This means power is still running through the amplifier with an insufficient power supply.. only 2 inputs instead of 3 are working. Wouldn't I might burn my amp to crisp??

The manual is showing a different fused-power circuit than just an inline fuse to each +ve input.

May be i'm confused!! Help me out guys. :Jim:

i dont fuse between battery and amp. 2ft runs of 1/0. Cant really help you but i would say if one went, the other would probably follow right after. Odds are against that happening i would think

I would hope the other 2 blow immediately after the 1st zayres29, but you know how with some built-in fused amps, if one fuse blew, the amplifier would stop working, and you find the other fuses are still okay sometimes.

I do too, I have almost 2' long power runs from battery to amp strangeduck! I'd like to not to fuse them, believe me, but I can't afford losing it right now.

the amp will try to start pulling the full 600a through the other runs thats why i said they wont last long just because every input isnt hooked up doesnt mean the amp doesnt still want 600a of current 300a through a 200a fuse will burn it

Btw that was the first person. Ever banned by me while dropping a deuce. Feel privileged

This is my logic. If the fuse blows then there is already something wrong with the amp or you are running it below it's rated impedance or you are abusing it somehow. I only fuse to protect wire. Call me crazy.

Wires are already cut, fuses/holders bought and on their way lol. I got no choice now!

Nothing wrong with what you said at all.

youll be fine with three fuses, and fusing is fine for the run to the amp. I just don't do it. But i think a lot of people do. I'm just a misfit.

Fuse or not to fuse ... This was the most mind-numbing decision I had to make. I was kinda of embarrassed to fuse a 2 foot power wire, honestly.

I don't trust my F@#king hand sometimes, that's the only reason I chose to fuse.
