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?

how about this bussman fuse?

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...??!!

ok,i had gotten a set of 12"MTX roadthunders,and 2 amps.1 MTX204 4 ch. and a lightning audio 250.1 amp.i got a walmart type amp install kit.i hooked the mtx amp up and speakers ,worked fine,decided to try the lightning audio out and it hit alot harder than the MTX.i turned it up a few times not for long just testing it out.i went to another song and the subs was not playing anymore.checked the amp the protection light was on,i touched it it wasnt even a little warm,unhooked it all starting with subs and rehooked  still the same.hooked the MTX back up worked fine.took apart the lightning audio and no burnt spots ,smells ,or anything to assume its blown..all fuses are good.there are 2 15 fuses in amp and 1 30 in power wire,what is it ..thanx in advance

Chances are the amp has one or more shorted output transistors.   Do you have a digital camera and a digital meter?

yes i have a digital camera,and can get a volt meter,do you just need a pic of the board,nothing on it has any sign of burns.but what are the pics needed any close ups of any certain part.and what do i check with meter and what should it read

ok idiot (no pun intended) i went out and hooked it up and the protection light popped on and the wire fell out so i put it back in and it wasnt on,hooked it to the subs and its got sound but i turned the gain,bass boost down,but im not able to turn it up at the moment,i did turn it up half way for a few sec.and sounds fine,so my question besides my others could my fuses be weak so before it pops them it goes in protection mode.or its got a bass boost on with the dbs on it,gain,and crossover,..im not sure what ohms my speakers are or my amp if its putting to much of a load.thanx for any and all information

Is it a 2 channel amplifier?  Is it bridged on the 2 speakers?  If yes to both questions, you really need to find out more about your speakers.  Or if that is not possible, connect one speaker to each channel of the amplifier.   You can not bridge the amp into a load less than 4 ohms.

the MTX subs are discontinued i can find some info about it the 1most helpfull and this is my acual set up box and all.it says its 2ohm,but what im wondering is it says 100-400 rms does that mean it can hold 400 rms or is it a 100.100 watts dont seem like alot of power...the website i found any info is https://www.crutchfield.com/p_236RT12X2D/MTX-Road-Thunder-RT12X2D.html?tp=112&tab=morephotos&pi=1&display=L.my amp is 1 channel and my subs are wired together to one terminal amp seems fine don't know what ohm the amp is ill check.i have hooked amps and radios and subs up before,ive just never knew that the ohms were important to match up.if you could sum it all up with last post i leave you alone,thanx a mill.
