amp shuts off

I have a 12" Alpine Type-R and a Kenwood KAC-8104D amp. With a 4 gauge wiring kit and 80 AGU fuse. Do I have do match the fuse on the amp and the fuse for the wiring kit? My amp has a 40 fuse. The fuse inside the fuse holder (80 agu fuse) is a little damaged, one of the metal cap on the fuse is really loose to the point if I pull it, it will separate for the glass part. And looks kind of burnt inside one of the caps Both ends of the fuse suppose to touch the metal right? Well both ends can get loose and sometimes when I put them together, I see a sparks inside the fuse, that is when my amp works. But as soon I play my music loud, it stops working. I know its something wrong with the fuse or the fuse folder. Please help me.

Get rid of the Gold Fuse. You will be much better off with a Buss, Bussman or LittleFuse branded AGU 50 amp fuse.

get a 50 AGU fuse and this will solve my problem =]? why think this happened?

If it is an actual Bussman fuse and you want to pay 3.22 for a fuse you can probably buy locally for 2.00 plus tax, then go for it.

where can i find those fuses? im not going to any local audio store store around because they think i was born yesterday. the other day a guy try to sell me 1 40 fuse for 5 dollars, lol. and 4 for 20 dollars. so im guessing they should have them at Kragen? Pepboys?

Pull the trigger...Alot of stress over 3-5 bucks...should last awhile...??!!M.E.C.P & First-Class
