Upgrading amp fuses

[Dub7sonoma Premium Member]

Just saw it was wired to .25.
Have fun toasting the amp when you increase the fuse ratings.

I have no more advice to give

Don't be skeerd

three 30A fuses is probably already over-fusing. 3 40A fuses probably will not protect the amp, anything bigger and you might as well do what someone suggested on page 1 and jam a penny in there or make some jumpers. If you're trying to break the amp why use fuses at all?

here's what i don't understand, you know what you're doing and have all that great expensive equipment - yet you have to come ask us where to find a fuse?

I just put 40s in it today. But I was looking for 50s

Sorry, I misread. I think they only go up to 40A: ATO Series - Blade Fuses Automotive Aftermarket Products from Fuses - Littelfuse

If you'd want to fuse higher you'd have to wire a inline fuse holder in place of the fuse and use a different type, like maxi or agu.

3 30amp fuses is what the amp originally came with. And I'm trying to keep fuses so if the amp does short internally they will blow there instead of the amp having a total melt down. And who said I was trying to break the amp anyways?

OK then. Just jam a penny in there you'll be fine.

smh

You're FORCING it to have a total melt down.

But not trying to break the amp -- NOOOooo.

Nah it'll be ok. Hasn't had a problem yet. It doest even get that hot

Here is a thought.maybe it's blowing fuses because that amp is not .25ohm capable.

A bunch of these and solder a were to them together to create a jumped

You can pick up some 50a vehicle mini resetable circuit breakers that will fit in the amps fuse slots ......150a's at 1/4 ohm should be fine plus they reset them selves when they pop so no more replacing fuses....

Lol. Next started thread by OP: "Why did my amp blow?"

It is obviously .25 ohm capable. Been doing it for about 2 weeks now. Maybe not on factory fusing but the 40 amps replacements are holding fine.

Sweet. I didn't think of that. The 40 amp fuses are holding for now, even on full song demos. Gonna do some more burping and metering this weekend
