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.

Can't really find anything about them but maybe if you contact Legacy and beg a little they might have a circuit diagram hiding away somewhere. Here:Legacy

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,

Constant thumping


Theres most likly an open ground printed circuit trace on the Printed circuit board on the bottom. first clue is You said your girlfriend disconncted and blew the fuse. You gonna have to ytake the amp apart and totally disassemble the PCB off the rails and everything unless theres a bottom cover. It may be an obvious burn or could be hidding under the green paint of a trace?? Goos luck
