Melted power wire
I was taking my equipment out of my truck to take it to the shop and I pulled the inline fuse under the hood. I noticed that the clear plastic fuse holder was cracked the power wire after the fuse was all brown and looked like the outer cover was starting to melt. The only thing I can think of is that the fuse is too big for the power I'm running. I'm running about 500 watts rms 800 peak on a good day. And the fuse is a 50 amp. Is that too big or what else could have caused that to melt? I thought the fuse was supposed to blow before anything melted or shorted out.

Re: Melted power wire
I had to go find my old amp kit box. It was 8 gauge and it originally came with a 60 amp fuse, so I must have picked up a smaller one somewhere. Is 8 gauge too small? When I first started building my system I asked the guy at mickey shores and I told him everything I had and he said that should be good. On the outside of the box it says up to 300 watts. So If my amp is 760 max I should still run under 300 rms. Right?

Re: Melted power wire
How far is your fuse from the battery?
8g power wire is fine if you're only running 1 amp thats 300rms. If I remember right, I had a 40amp fuse with my 8g wire. I was running like 400 maybe 500rms w/o any problems. I've heard of that when you overload a wire like my friend did running 2 amps off a 8g wire. The whole thing melted and blew the fuse.

Re: Melted power wire
No. the amp kit came with a 60 amp and when I pulled it apart the other day I had a 50 amp in there. So it should have blown sooner.

Re: Melted power wire
I would have to doubt that. Who ever make the wires knows it has to connect to the battery, which is under the hood and they should know it can get hot under there. Plus were it was burnt was right on top of my radiator resivior. And that was plastic so if the wire melted I think the plastic resivior would have melted first or looked discolored which it wasn't. And the whole wire wasn't burnt. Only about 3 inches right after the fuse holder.

Re: Melted power wire
Your ground might have something to do with my friends ranger melted the power wire about 6 inches and it was becasue his ground 3' long. Made it 6" long and he hasnt burnt it up since. Either that or you have to much power running through the wire.

Re: Melted power wire
The amp is in the extended part of my truck right under my enclosure. And the ground wire is only a foot long at the most. I un-bolted the seat and sanded the paint off and bolted it back down, so it should be getting a good ground.
