Give it power, ground, and remote turn on and put a sub on it quick it should kick on and stay on and push your sub. If it doesn't it's probably not going to work and isn't worth fixing. Personally I wouldn't buy it in the first place, save a little more cash and buy a quality amplifier. That's actually one of the most important parts of your system.

SOURCE: 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

If the fuses were the problem then you would be replacing them all the time. Fuses are only good once - and are only in place to protect the circuitry from damaging overcurrent situations.

More likey, the problem is a thermal protection resulting from over-driving the amplifier. What impedance are the speakers you are running? Does the amplifier support that impedance? Typically, car audio runs 4-8 ohm impedance. Many amps have a switch to place the unit in the proper impedance mode.

Check your wiring. Do you have it wired correctly?

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.

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.

600w legacy amp


9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck

Problem with legacy amp


I would check the RCA preamp wires connecting the stereo to the amp. If these are loose or broken, it could cause you to lose your sound.

Does the amp show signs of life, such as clicking on, an LED turns on, or anything like that?

Has anything else changed between the time it worked and didn't work?
