I have a dual XIA3145 580 watt amp that keeps blowing fuses

I have a dual XIA3145 580 watt amp that keeps blowing the 2 20a fuses located on the amp. I've checked all my wiring for shorts. I came up with nothing my wiring is fine. The fuses blow about 2 seconds after receiving power no music is even played through it. So is my amp toast or is there a solution for this?

Generally, this indicates that there's at least one shorted output transistor.

Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still blows the fuses, the amp almost certainly has shorted output transistors and will need to be repaired.

I'd recommend using two 10 amp fuses. The amp will power up with 10 amp fuses if there is no problem. If there is a problem, there's less of a chance of doing more damage by using the 10 amp fuses.

Let me know if you have any other questions.

Why do the fuses blow out every time I plug it in


watts divided by volts equal amps so 400watts devided by 12 volts equal 33 plus amps if wires and fuses wont handle 35 amps they will blow to keep from burning up the wiring of your vehicle

Coleman furnace dgaa077bdta


The control fuses keep blowing tells me one or more of the control that operate the control on 24 volts is malfuctioning. Most controls operate at about 5 watts and on a clamp on amp meter normally pull about 0.2 amp (p = current x voltage, 5 watts = 0.2 amps x 25 volts) I install 75 watt 24 volt transformer with a resettable overload to save on fuses. I reset the transformer and quickly go to the controls and determine the amp draw. When I find the one >0.2 amps I found the problem. The things to check is the emergency heat sequencer, fan control sequencer, reversing valve for heat pumps, main contactor on the condensing unit and any other 24 volt control loads. I have had to replace the themostat wire because the increase current for the thermostat wire can cause the entire length of wire to form a long heater and cause insulation degradationa and cause the thermostat wire to short out and blow the fuses.
Hope this helps

Electric Water Heater blows fuse, but only every few years


Your residential water heater is not 9000 watts. Or it would blow the fuse every day and melt the wire. Instead, you have dual-element non-simultaneous 4500 watt water heater.
http://waterhatertimer.org/How-it-works.html
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html
Look at label for 'total connected watts'
http://waterheatertimer.org/images/Whirlpool-energy-smart-watt-rating-IMG_2600.jpg
25 amp breaker or fuse and 10 gauge wire is minimum acceptable for 4500 watt water heater.
http://waterheatertimer.org/Color-code-wire.html
Troubleshoot blowing breaker or fuse:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#trip-breaker
Why does it blow fuse once each year?? I don't know.
Fuses and breakers trip when overheating occurs on wire.
Each fuse or breaker is rated for heat, and over time, it will get hot and then cool and then get hot again ... this action weakens fuse or breaker.
To solve problem: install 3500 watt elements (and clean sediment out of tank). Wire will run cooler, and fuse will last longer. Whole fuse box will demand less power, and run cooler, and will last longer as a result. So there is less stress on electric service panel.
http://waterheatertimer.org/How-to-replace-water-heater-element.html
3500 watt element will heat water to same temperature, but takes longer. For example: 4500 watt heats 21 gallons per hour, while 3500 watt heats 17 gallons per hour.

Brake light fuse keeps blowing in my 1997 Suburban only when towing trailers.


If the fuse blows on different trailers then it's all down to the vehicle. You either have incorrect wiring on the vehicle, a short OR the fuse is not of a high enough value to cope with the additional brake lights? You could try removing all the trailer bulbs EXCEPT the brake lights - e.g. if it's trying to power up the indicators too? That would stop the fuse blowing...... OR remove the brake bulbs from the vehicle & see if it operates the trailer without blowing...... Check the total wattage of ALL the brake lamps & see if the fuse is actually of a high enough rating? Be aware though that increasing the value of the fuse could cause damage elsewhere! As a rough guide a 25 watt bulb will pull around 2 amps at 12 volts - so 4 bulbs may pull up to 8 amps & clearly blow a 5 amp fuse! If in doubt take it to an auto electrician...... The wiring needs to be correctly protected!

Just bought 2 12 in d3 dual 2 ohm subs with d5 600.4 amp. Need to know how to wire subs. They were in a box already I assumed they were wire at 2 o When i hooked One up to my amp it hit really for Jus...


what wattage are the subs and amp? if your subs are more wattage than your amp, your amp will blow fuses as cant handle the output to your subs. for example. you have 2 500 watt subs and a 300 watt amp, that is no good as amp isnt powerful enough. if you have 2 500 watt subs you need at least a 1200 watt amp to power them both. 200 watt more than the combined wattage of subs as amps should never be turned up to max as they tend to blow and overheat more quickly. 80% volume on amps is reccomended by installers and manufactures.

1984 ford ranger keeps blowing the running light fuses. when i let it sit at idle it won't blow the fuses but as soon as i start driving with in 5 mins or so it blows.... any ideas?


short in the wires will need a wiring diagram and ohm/volt meter to locate the problem, test lights work well to.
you will need replace the fuse with a light bulb so that the power will not go away. and you will have to search for power going straight to a ground source.
usually a raw wire from rubbing somewhere. can do a quick visual inspection first for the obvious, and then use the meter at certain points till you find a volt drop.
