Suddenly popping inline 40a fuses.


Recommended Posts

Posted

I have a Rockford 600.1 amp that has 2 30a fuses on the side.

For the last 3 weeks I have been playing my system pretty hard and everything has been fine. It was tuned with a DD-1.

Now all of the sudden today I have blown my 40a inline fuse running off my battery. I replaced it with another 40a fuse and 5 minutes later it popped again. Why? What should I do?

The only thing that changed was that my battery died and I jumped started it at a Jeep show I was at today. But it blew about 2 hours after that.

you have a 40 amp fuse on an amp that has 60 amps worth of fusing. put a 60 amp fuse in the inline fuse holder

I dont mind upping the wire or the fuse ratting if everything else is fine. But why all of the sudden?

maybe some strands of wire came loose. check ALL connection points. from the battery all the way to the amp terminals.

I have and everything seems fine. Should I just go ahead and up the fuse to a 60? Its not like the fuse is popping instantly it is taking a few minutes at full power but I keep going back to it was fine for the last 3 weeks.

What size is the wire? derp

Just use a bigger fuse.

And the fact more than one person agrees does not make it a circle jerk, it makes it a bukkake scene and you're in the middle ;)

Chick took 3 shots of Jager, and then, pissed in my mouth..
