Eating fuses...

[yenwen 10+ year member]

Whenever I'm blasting my sub my fuse will blow in less than a minute.

I'm running 80amp AGU fuse with 4 gauge wires and a PPI 2200 amp. What could cause this? Is there anyway I can fix this problem? I'm not sure but I think my ground wire is a 8 gauge.

Oh and I'm looking to have someone build a custom box for me that involves bending plexi glass.

the fuse is located nxt to the battery. I'm pushing a PPI pcx 2200 which is 800watts RMS bridged at 4ohms. 4 gauge should be able to handle that much power but would an 8 gauge?

Bigger fuse DUH.

i would upgrade that ground wire and bump up the fuse to 120a or so

i had this same problem weeks ago, 4gauge wires, distribution block w/ agu fuses. 60 amp agu.. blew... went to 80 amp agu... blew, went through about 6 fuses in 3 days..

they also only blew when i turned the volume up to about 75%. Gave up on the agu fuses, bought a anl fuse distribution block, same size [80amp] fuse, havn't blown a single fuse since.

agu fuses = shit

upgrade to anl or maxi imo

edit: agu fuses only goes up to 80amp max. so going up would mean upgrading to a different type of fuse , anl can take alot more heat too since theres no glass 8)

I would put a clamp on it...see what your current draw is, so you will know what exactlly is causing the fuses to blow.

I had a 100amp AGU the shop put in I ate that in about 2min. What do you mean by Clamp?

What if I'm actually using 8gauge wires.....????

 

[Lance 10+ year member]

ohh its an inline fuse,

but none the less, if the fuse is blowing its more than likely because of a current draw in excess of its rating,

What does the PPI amp recommend to be fused at?,

A clam on meter would tell you what is the current draw

 

[yenwen 10+ year member]

Honestly don't know what PPI recommends it's an Old amp before PPI got bought out by directed

so you lied at the beginning...??//content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif

run 4ga with about 120a anl and you should be golden (battery and ground)

 

[85Caprice4d 10+ year member]

why did you say you were running 4ga when you are running 8?

you worried about being flamed?

Dont use bigger wire if yo u dont need it(even tho it doesnt really matter), dont use smaller wire if u need bigger wire, and dont use one ga wire for power run and a smaller run for ground...

i dont know the numbers on this,

but oga handles the most

4ga is next

8ga

ect.

if ur running as much or close to as much as 4ga can run max, that is way to much for 8ga....so if your power run is 4ga, and ur ground is 8ga, your gonna fry your ground wire...

(correct me if im wrong)

make all runs the same size - 4ga minimum.

i would suggest finding the sticky that sais how big of a load each cable size can handle and use the applicable wire. make sure any size of wiring you use is capable of handling what your throwing at it.

I said that because I think I'm running 4gauge but my friend thinks I'm running 8gauge.
