fuse keeps blowing

[brougham]

THIS WEEKEND I HOOKED UP MY SUBS AND THE FUSE KEEPS BLOWN I HAVE TO PUT A NEW FUSE IN EVERY FEW HOURS I DONT KNOW WHAT THE PROBLEM IS. I CHECKED ALL THE WIRES AND NITHING SEEMS TO BE GROUNDING OUT . ANY IDEAS ANYONE?

[ilterzo84]

you prolly have too small of a fuse for the amp that you are using.

Two things:
1. Lose the caps, it's hard to read and is considered "yelling" in the online world.
2. Can you give us specifics on your setup? Amp, subs, number of subs, grounding point, fuse size, even the wire guage used.

1000w amp the wiring kit came with a 30a fuse 2 10" kenwood and i believe its a 8 guage power wire i grounded it in the trunk to the bodyand a line out converter grounded to the same place
sorry for the caps didnt relize till i was almost done typing and didnt feel like re typing it

[Blackhawk]

Do you have a good connection with that body ground? Make sure there is no paint and the metal is shiny where you ground it. If you had grounded it to something thicker a self tapping screw would have worked for smaller loads, such as adding lights. Is that 1000w peak or rms?

[SilverBane]

If it is a true 1000Watt amp, 30 amps wont be enough, nor will 8 gauge.

What kind of amp is it (model number)?

[Rainbow1616]

If its an 8 gauge power wire it should be a 40 or 50 amp fuse. Thats what I have on my 900W amp and have never had a problem.

[SilverBane]

You should not simply 'switch out' a fuse for a bigger one. Not all 8 gauge wire is the same.

[brougham]

i posted before what kind of amp it is and nobody heard of it so its probly not a tru 1000w i put a 30a fuse in cuz thats what it came with but i was pretty sure it should have been bigger im going to relocate the ground wire and see if that helps

[Blackhawk]

How long is your ground wire too? It shouldn't be more than something like 18".

When it comes to power wires, it is all the same.

10 gauge is rated at 30 amps. 8 gauge can handle 50 amps all day without getting warm.

Thats funny, according to the american wire gauge standard if its rated 8 gauge the absolute minimun current it will handle is 40 amps and thats the lowest grade. Most anything used now is 50 and up.

If you continue to pop fuses you either have to be grounding out somewhere or theirs a problem internally with the amp.

[ga5speed02]

try using 4 ga wire

Yes, this is according to the AWG standard (American Wire Guage), but you also have to take into consideration that A LOT of companies aren't truthful about their wire sizes, yes they may be badged at 8 or 4 gauge, but some are not the actual guages. Look at Scosche install kits at walmart. They were selling them as a 4 guage kit, but now they are selling the SAME kit as a 5 guage kit. So you can't always trust what the wire is marked as 8 guage, doesn't mean you can put a larger fuse than what was supplied in the package since you're going on what the AWG standard says you can have.

[tenspeed]

The gauge depends on the area of the wire. How many amperes it can handle depends on what kind of insulation and what kind of installation.

A wire hanging in free air can carry more amps than a wire packed in a pipe with a bunch of other wires.

Feel the wires for heat especially at the distribution blocks and terminations. If nothing is hot, put a bigger fuse in it.

Well if its a true 1000 watt amp no way it would have a 30 amp fuse for it, so i would check that out and if it is a 1000 watt amp i would run 4 gauge for sure. I have a memphis 1000D and it has 3 30 amp fuses and i run 4 gauge and never had a problem.

[Rainbow1616]

Yes you first need to check the wattage specs. Amps are rated differently. What do you mean by true 1000 watt amp?
Is it 1000 watts RMS @ 4 ohms?
I have a 1000 watt amp also but thats the peak rating not the rms.
The rms of my amp is 300 watts @ 4 ohms which draws about 25 amps @12 volts(300/12=25). I use 12 volts instead of 13.8 for a little margin of safety.
so yes check your amp specs or post the model number.

[xtantman]

What i was meaning by a true 1000 watt amp is a 1000 watt class D amp that is a name brand amp that doesnt have a 30 amp fuse. There are so many amps that say they are a 1000,2000, and so on when they have tiny fuses and cost like a 100 dollars, what i always say u get what u pay for. Not being cocky just telling the truth.

[brougham]

i got the amp for free its got 4 25 amp fuses on it donrt know if that means any thing but i relocated the ground and seems to be fine now

[xtantman]

So ur amp has 4 25 amp fuses in it but ur wire kit had a 30 amp fuse? Well its not rocket science then u need at least a 100 amp fuse on ur wire kit then.
