Amp keeps popping fuse.

[TaylorFade 10+ year member]

I have a Cadence A7HC running at a 1ohm load. The amp has no onboard fusing but I have an inline from the battery and a 60A at the distribution block for it. Under pretty normal listening conditions it is blowing that 60A fuse. The amp is not getting hot and it has yet to go into "protect" mode. Do you think it's safe to go up on the fuse? Not 100% on the rated output of the amp but I've seen it rated at 1200-1400w @ 1ohm. Is 60A normal for this rating?

P.S.- when I say "normal" listening conditions, I mean rap for the 45 min. drive to work.

why not a 125 amp fuse?

voltageXamps = watts. 100-125a fuse is what you are looking for if rated at 12-1400watts.

You can definitely blow a 60A fuse with a 1200 watt amp.... I've done it a few times

Lol. Manual. That amp is like 12 years old.

But thanks for all of the info. Exactly what I needed to know. 100A will be going in tomorrow. Thanks again, CA.

I ve seen amps like that pop a 30 amp fuse just trying to power up..go with at least 100 and see what happens...

Hey I'm running a SAZ-4500D and it keeps blowing my 30 amp fuse. Helpz0rs!!! Wtf dude. Lol. I was so right when...... I mean ecrack was so right when he dubbed you "TaylorFail". JK man. You're going to have to upgrade fuse blocks. You're probably using an inline fuse. The biggest they make are 60 or 80 I'd guess. Just go to your local audio shop and get an ANL fuse block and ANL fuse. 100 amp SHOULD do it.

Would you care if I saw a picture of your AGU fuse larger than 60 amps?

lulz, you never said specifically AGU fuse. I was just being a smartass. ANL FTW.
