I have a blown 5AG60A fuse that was in my fuse block. My sub amp was connected to it and it has 3 30A fuses so I was wondering if I could put in a 5AG90A fuse if one exists?

5AG meaning an AGU glass fuse?

yes, thats a glass fuse, but they dont make them that big.

an 80 amp one might work...

Personally I woulnt use anything bigger than a 50amp AGU. 60's seem to melt inside but they still look like they should work. 80's are worse. If you have that much current then go to a "waffer type" ANL fuse

Agreed - either move to a fugly MAXI fuse or go to an ANL wafer. Might find wafers at 80amp but 100amp is more common. Doesn't much matter as the amp is fused anyway.

links please so I know what your talking about

I have the one power wire from the battery going to the trunk then two amps, only reason why I have a distribution block.

what caused it to blow was I didn't give the system much time to warm up

apparently 60A fuses are the largest ones sold for a http://www.futureshop.ca/catalog/pro...d=&newdeptid=2

I think they should have 80's, but the reason behind them melting/going poo is more because of the build quality of the silly things. I don't recall ever having heat problems with AGU fuses, but that's probably because I pay $2+ per for a fuse I know isn't going to heat up on me.

But yeah, it's somewhat annoying to have a 60 amp AGU running a single power wire to an amp that has a 90 amp rating.
Maybe have 2 runs of fused power wire and fuse them at 40 or 50 each?

I use an 80 amp AGU fuse.....
