the formula is amps= watts/volts 680/12= approx 60 amps-rounded up

I = P/E Current = power/voltage

Therefore 25 watts of power divided by 12 volts if that is the battery voltage, equals about 2 amps. You should try a 3 or 4 amp fuse..

Calculating necessary breaker size using ohms laws, says 3000 watts at 240 volts would use 12.5 amps and most range circuit breakers are 30 amp so it should be find

I can't find an online manual for the model of the appliance you are talking about, so I'm unable to figure out the wattage it draws. Nor do I know where you are in the world and the voltage you are running at, so I can't tell you straight off. But I can tell you how to figure it out very easily:

I imagine that know what your main power supply voltage is (either 240 volt or 110 volt).

You can look at the appliance and there will be a data sticker with the wattage rating on it somewhere (or it will be in the install/Owner manual).

Now you have these 2 bits of information we can do a simple sum:

Watts divided by Volts = Amps

Therefore example calculations look like this:

If you have a 500 watt appliance on a 240 volt system 500/240 = 2.083 so use a 3 amp fuse

An appliance with a 750 watt motor on 240 volts: 750/240 = 3.12 so use a 5 amp fuse

A 2KW (2000 watt) appliance like a hot air blower on a 240 volt system: 2000/240 = 8.33 amps so use a 10 amp (or more commonly 13 amp) fuse

A 500 watt motor on a 110 volt supply 500/110 = 4.5 so use a 5 amp fuse

A 1KW (1000 Watt) appliance at 110 volts: 1000/110 = 9.09 amps so use a 10 amp (or more commonly 13 amp) fuse

etc etc etc.....

If the sum comes out below 13 amps, you can use a 13 amp plug. If it doesn't you need to hardwire it into a proper cooker supply.

Not knowing the model of the mixer you are talking about, or where you are in the world and the voltage you are running at, I can't tell you. But I can tell you how to figure it out. Simply do this:

You obviously know what your main power supply voltage is, either 240 volt or 110 volt

You can look at the mixer and there will be a data sticker with the wattage of the motor on it

Watts divided by volts = Amps

Therefore, if you have a 500 watt mixer on a 240 volt system 500/240 = 2.083 so use a 3 amp fuse

a 750 watt motor on 240 volts 750/240 = 3.12 so use a 5 amp fuse

a 500 watt motor on a 110 volt supply 500/110 = 4.5 so use a 5 amp fuse

etc etc etc.....

Hope this helps

outputs also blown, go to ebay and buy a better amp form the same price you would have paid for pyle to fix that one, just keep playing with that one and you will get better at repairs, thats how i learned to fix amps.

just wondering how you connected the amp . you should do the following steps

1 battery cable with right size fuse at battery

2 remote wire from radio

3 rca cable from audio out from radio

4 ground the amp to a good clean piece of metal

then make connection on the amp

1 battery or power cable to the 12volt connector on the amp

2 remote wire to b+ or rem on the amp

3 rca cabel should be pluged in the channels are using cause you tell me that the amp is 4 channel

from the model numbers

4 clean and scrape off paint on the metal surface you are going to install the ground cable from the amp . make sure your ground is no more than 12 inch max. and is the same gauge as the power cable

5 . run your speaker wires to the amp and make sure your ohm load for the subwoofer is 2 ohms or 4 ohms to make the amp work proper .

if need help on anything email me @ caraduioquestion@gmail.com

well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

The size of the wire affects the performance of an amp, but the amp should still turn on. 12 volts is 12 volts. So you tested with another amp, on the same wires, and it works fine.The only thing you can really check on the new amp is the fuses in the side. If those are blown, then you should be able to (Unless the amp is fried, and that's why it blew the fuses in the first place) fire it right up. If the fuses arent blown, and you have all your power, and ground, and still nothing.. Well then in that case the amp is just bad, and regardless of the wattage, you just don't fix a Pyle amp.

is it hot when it shuts off? from what you just described sounds like amp could have the "ohms" too low on a channel. Check you speakers with a meter. They should be no lower than 4 ohms.
