I think the fuse between my battery and my Capacitor for my audio amp is fried. I'm not getting any audio out of the subs, the cap's LED display isn't lighting up, and the light on the amp is very dim if it's lit at all. I checked the fuse before I went to work this morning. One end of it is a brownish color almost like rust color inside the tube around the edge of and into the conductor (it's a cylindrical fuse). The portion of the wire that runs through the fuse that i can see looks fine, but it could be burnt off down where the brown is in the conductor end where I can't see. Looks like it's a 50 amp fuse, FYI. I guess I'll need to pick up another one.

def blew the fuse Dan... I lost count of how many I've blown installing neons and stuff... I buy 'em in bulk now..hehe

Yeah, it was the fuse. I have an 80 amp now instead of the 50 amp. Running 4 guage Rockford Fosgate cable.

Whoa you stepped up 30amps? That seems like a considerable jump. Do you have more than one amp running on your system? just seems like you shouldnt need that much for that kicker amp you had.

I agree. Its a good idea to go up a little at a time otherwise you could have too many amps for the wire but not enough to blow the fuse, melt the cover and wire, get an arc and insta flame. seen it before, not pretty. I personally have a 140 amp circuit breaker and only popped it once when i blew my subs. thank god for warranties.

The only reason I'm using the 80 amp is because Advanced auto doesn't have a 50 amp and Wes had a bunch of 80'ss I'll probably go back down to at least 60 next time I make it to a car audio store.

Is it a glass type fuse or one of those massive fuses that is basically an enlarged fuse type that we use in our fuse box?

 

[dant98]

Glass Cylinder.

I looked up the safe current carying capacity of 4 gage wire. You're ok as far as that is concerned, 4G wire can safely carry 85 amps. I dunno about your amp melting and stuff though, but the wire will be ok

Try a 50A fuse and no capacitor.

OK, this past week I ran into a similar problem that Dan had. I kept blowing fuses. I had a 30A ATO blade type fuse, the same that is on my amp. I just upgraded to a glass cylinder type fuse, but could only find 60A fuses. I run 8 gauge monster wire that I am guessing is around 10-15 feet in length. Am I overshooting the amperage on this wire?

If you are unfamiliar with my set up here it goes:

30A draw Alpine amp=MRV-T500 256W x [email protected] 12V or 352W x [email protected] 14.4 V
150 mA draw Epicenter
1.2A draw cooling fan
.35A draw cooling fan
no draw? .5 Capacitor

I recently changed one cooling fan from a .35 A to 1.2 A fan. This is all I changed and it would blow fuses(at the battery) after like 3 minutes on full volume. Should I try to find a 35A or 40A fuse or am I going to be ok with the 60A that I upgraded to?
