i had it all in a 93 ford contour and i drove it for about 10 maybe 15 minutes and it played great.. and i parked it cause it was late and the next day i was playing it without it cranked and the fuse blew..

what kind of fuse do i need to get or do i need to get bigger wire?

go 4awg man will help and fuse it with like a 150 amp fuse you'll be good.

What size fuse blew?

 

[gfree569 10+ year member]

idk what size it was.. thats the problem.. but it comes in those standard 5g kits at walmart..

probably a 60amp or somethin... Throw a 80amp fuse in there and see if that blows.

Does anyone actually have a clue in here? Check your amps owners manual and see what the manufacturer says you need for a fuse. And that crap 5 ga wire is more like 8 gauge wire but with more insulation around it to make it look bigger. One of my buddy's bought the same stuff, it's cheap for a reason, real copper wire is expensive and Walmart is all about being cheap. With a good amp the fuse ratings are generally 10 amps per 100 watts. If that amp really puts out 1200 watts then you'r gonna need something like a 120 watt fuse, but READ the ****ed manual FIRST!!!!

kits from walmart usually come with a 100 amp fuse

yeah, and kits from Walmart have the lowest grade and lowest strand count wire too. When your looking for power wire your looking for the wire with the highest amount of copper and the most wire strands. Thats something you'll never find at department stroes like Walmart.

Strand count is only for flexibility.

Cross sectional area determines power handling.

I'm sure if you asked in the right forums you'd find a 1000 guys that will tell you differently. The more wire strands the more power will be allowed to pass through that wire. Yeah, it makes it more flexible, but that plays no part in a reason for buying a high strand count wire. Electricity travels around the outside of each strand, the more strands, the more power can flow and with less resistance.

how do fuses sound when the blow?

lol, are you serious? Depends on the size fuse, you either won't hear it or you'll hear a pop noise.

Skin effect happens with high frequency AC, not DC. DC current flows through the entire conductor, therefore the cross sectional area will be the greatest determinate for power handling. You also have to take into account the material and length of the conductor for exact power handling.

I've never heard there was a difference between the skin effect with AC and DC currents. The only references I've heard were about power wire, not speaker wire.
