im a no fuse virgin .

To my knowledge any that don't specifically state a fusing limit or use the fusing to determine class. I havn't been in a sanctioned event in a long time though.

I havent been to an SPL comp in a long time either. Back when I did go to them once in a while (and SQ comps), there was a pre-comp inspection that insured the system was built safely, including the proper fusing setup. In either case, it sounds like we are on the same page here, finally. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i did it because i had no fuse holders. they come on the 11th. so ill wire it up then but i hear alot of people run without them. so i gave it a shot. also. guys keep a peep on my build. i have some really good stuff coming up //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Fuses have almost nothing to do with the amplifier. If your amplifier blew then it was going to blow regardless of fusing, however if it blows and shorts the 12V power to ground then you're likely to have a fire on your hands. Also if for some reason the wire grounds out (comes out of the terminal, pinched somewhere, etc) then that's also a great way to turn your car into a toasted marshmallow. The point is, you spend thousands on your car then hundreds (if not thousands) on your system, why would you risk destroying everything to save $20?

Being an engineer I'm always thinking about the worst case scenario so I happen to also carry a small fire extinguisher in the car as well...

While I do know how to tighten a screw down before, I've also had wire come out of the terminal before. Speaker wires, not power wires thank god.

But I just don't see why anyone would choose not to run a fuse... It's not there to protect the equipment, it's there in case something unexpected happens that's entirely out of your control. It doesn't matter how good your install is if a car crashes into you and the wire gets cut, shorts, and starts a fire because you didn't have a fuse. Just doesn't make any sense :\

And Rob, that is an AWESOME chair.

I hear a lot of people jump off bridges too. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

ok. me and "cat man" have the same amp. i just trying to narrow down some possible causes. my amp was going into protect yesterday, and i wasnt sure why. i thought it may be my remote had a short in, so i jumped the the remote to power input and yea it did so i changed. i havnt had the chance to turn it and check it to see if it fixed it yet... also the amp requires dual 4 ga power inputs & dual 4 ga ground inputs with each power wire fused. if one of the power wires were a little bit longer then the other, i figure it would cause the longer wire to have more resistance then the other, could that cause amp to go into protect as well?

What amp is it? Unless its a 4-channel or more, with separate power supplies (basically multiple amps inside a single chassis), it should not actually 'require' dual power and ground cables.

As for the longer cable length for one of the runs, you are correct that the shorter wire would show less resistance, and thus carry more current. Unless the length difference is significant though, it wouldn't cause any severe problems. And this answer is assuming its one of the fairly common amplifier designs that has multiple input terminals, but which are simply linked together inside the chassis to create one large input section.
