why does my amp keep blowing 60 amp fuses?

How do you know if its clipping? How did you set the gains/head unit/crossover (if it has a boost)?

Do you have an under hood fuse, less than 18" from battery? If so, what rating is that? As long as ur distro block is rated for it, I would increase that fuse to 80. Should solve your issue....

it's just a straight power wire ran from the battery straight to the distribution block and a smaller 4 gauge wire out the other side to the amp. and yes, I seen that video where it ran at 453 watts mono at 2ohms. I believe it was 453. something like that. and i'm running a stock alternator and a single battery. it doesn't clip. just when the bass hits real hard after about 10 to 20 seconds, it pops the fuse.

How do you know you're not clipping? Since you don't have a DMM I know for a fact you don't have an OScope or a DD1. Are you using any type of bass boost? And if it calls for 60 amp fuse at 2 Ohm then it will blow it at 1 ohm.

this page about half way down explains the type of amp I have. a "high current" amp.

I base troubleshooting on a per scenario application.

Keep posting general rules of thumb and suggestions to generalize everything is exactly why you are having problems.

You need to go get a DMM to troubleshoot.

Any other amps connected to the distro, or are you just using that as a reducer?

yes. the only amp on the dist. block. i'm using it because the amp itself doesn't have fuses on the outside.

Current = amps....

Put an 80 in that ditsro (as long as its rated for it) and bump that Bish.

Confused... what does that have to do with anything?

hell. I don't know. I was asked to give info. so there it is.

Do you have a link to the distro block you have? Type, model, brand and so on....

Lol gotcha... Your trying to help and learn to trouble shoot. Thats a good place to be. Clipping is sometimes hard to hear by ear. Bass boost, dirty signal, bad music, low voltage, bad connections can all have an ill effect on clipping. If all your connections are good back the gain down a bit and see if the problem persists. An 80 amp fuse may not be harmful but if the manual is calling for a 60 then there is a reason. It could be stopping the amp from harmimg itself. Gain is not a volume knob and an amp driven into clipping can be the loudest its going to get.... but doesn't mean its the best way to set it up.

I'm interested to know what manual it is that's calling for a 60amp also.....

That amp is 25 years old. Way past it's prime and obsolete. At best a 400 watt amp running hard. Get a different amp from this century.

Or slap a bigger fuse near your battery on positive cable. Then fuse a 100a on the distro. If your blowing fuses after that your **** is set wrong.
