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.

2000 watt american legacy amp protection ligh wont go off


Same thing happened to me so I returned it for repair turns out it was an internal 25amp fuse on the output. Got it back an it sounded very weak now it does not play at all. Nothing wrong with my setup as I have now got an 800watt amp that is running great.

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.

Wondering why im blowing fuses


The most common reason for an amp (in good working order) to blow fuses is a speaker load that's impedance is too low. You may need to rewire your speakers.

Let me know if you have any other questions.

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

Optimum sound performance needed


1) legacy products are highly overrated and i have never seen one put out the power it claims
2) if you are running the amp bridged, you need to match the impedance of the speakers to the amps highest output impedance, otherwise your system will not sound all that great...

what size fuse or fuses does your amp use? what size wire did you install with (power and ground)? did you connect direct to battery or did you connect to a fuse block or similar? did you use a stiffening capacitor? does it sound like it is clipping when you turn it up or is it just distorted? what kind of box are you using for the speakers (ported, vented, sealed, bandpass)?

if you give me the model number of your speakers and your amplifier i can probably help you more, but with the information you have provided, this is all i can offer..

hope it helps,
trin
