    Never replace a fuse with a piece of wire. It's likely to cause an electrical fire.



    Disconnect the RCA cables from the amp and disconnect all of the speaker wires from the speaker terminals of the amp. Reinstall the proper size fuse and power the amp up. If the fuse blows, the amp needs to be repaired. To better protect the amp, install a total of 40 amps of fuse. If it blows a total of 40 amps of fuses with no audio output, it's definitely damaged.



    At this point, it appears that the amp only has shorted output transistors. If you continue applying power to it, you're likely to do more damage. At that point, it may be less expensive to replace it (looking at the prices on the web).

Amps got a dead short internally. Take it to a car audio shop, have them put it on the bench and confirm. If it's new, exchange it. Hope this helps

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty.

I need to know the size of external fuses for a american legacy amp 2000 watt 2 channel 1990


25 to 30 amp fuses will work great, anything lower could possibly blow a fuse when a good bass note hits even if there is nothing wrong with the amp. Hope this helps.

Capacitor not working properly


the power side has to be in line with the battery power side! The ground side to ground! The power that ran from battery (fused) to the amp power is used and cap is tapped in line, on that power lead! that way your amp gets power with cap charging and stable voltage to amp! taking stress off your charging system and better sound! good luck!

Just installed new steam shower, it produces steam for about 5 minutes and then blows the fuse


Based from your comments, a new steam shower that blows the fuse in five minutes. You could have installed a new steam shower that is much bigger than what you previously have.
1. For a 5000 watts steam shower at 220 volts
power must have a fuse rating of 40 amps, supply
wires of at least No. 6 AWG Type THW ; and at
110 volts a fuse rating of 80Amps, supply wires
of at least No. 2 AWG type THW.
2. For a 4000 watts at 220 volts, Fuse: 30 amps,
Supply wire: No. 10 AWG type THW. At 110volts
60 amps, Supply wires : No. 4 AWG Type THW
3. For a 3000 watts at 220 volts, Fuse: 20 amps
Supply wire: No. 10 AWG type THW; At 110volts
Fuse: 40 amps, Supply wire: No. 6 AWG THW
4. For a 2000 watts at 220 volts, Fuse: 15 amps
Supply wire: No. 10 AWG THW and at 110 volts
Fuse: 30 amps, Supply wire: No, 8 AWG THW

I have an american legacy series 2 1000watt apm


Check and see what size fuses it uses. Your watt power means nothing without good fuses. My suggestion would be to go buy 40a fuses and replace the ones you already have.

Car amp blows 12 volt wire fuse


the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse

What size fuse do i need for amp


start with a 50, may need to increase it if you are not using a large capacitor.
600 watts = 12x
x= 600 watts / 12 volts
x = 50 amps
