You need to pick up some wire. 1x Red-power with a fuseable link. 1x Black-ground, 1x 2 conection RCA wires, that will be of length to come from the back of your cd player to the place of your amplifier. and a single wire preferably BLUE to run from the MEMORY WIRE that is BLUE also and will be most likely marked on the back of your cd player. If you are trying to install this onto a stock car cd player, you only have a 10% chance it will work, because most stock stereos do not come with a RCA output jack on the rear. This set of wires can be purchased in a pack from any Walmart or car audio center.

Now take the RED WIRE With fuseable link and connect the end with the fuse to your Positive battery terminal. Now heres the hard part, you need to run this wire from inside your engine bay to your Amplifier most likely in your trunk, and to do so look for a Rubber grommet or any entry point from there into the car. After running the wire into the car, the running boards on the floor can pop out with a few screws and run the wire under the carpet, all the way to your Amp. After doing so leave that wire. Now you need to lift up your trunk floor mat and spare tire cover and look for a decent bolt that touches bare metal. THIS IS WHERE YOUR GROUND MUST GO. The ground - will need to have a good contact with metal because the amplifire recycles its energy out of the car. Now, you need to run the RCA cables and you need to run the MEMORY WIRE, this will cause you to take out your cd player and look at the back. Insert the RCA cables into the red and white holes that say Audio out or SUB OUT. Then you need to hook up the blue MEMORY WIRE from the back of the cd players harness to your Amplifiers MEMORY Port. After running all these wires the same way back as your power you can now hook up your Amp. The 12v+ needs to be hooked up to your RED POWER WIRE. MAKE SURE TO DISCONECT FROM BATTERY 1st!!! The ground wire will go onto the GROUND or - terminal on your amp. The memory insert should be between the power and ground or on the other side of the power. IT HAS TO BE HOOKED UP FOR YOUR SYSTEM TO WORK! the memeory wire is the on switch. Now plug into the RCA wire to the AUDIO IN, and your almost their. you need 2 wires for each speaker you use on this AMP. 1 + and 1- ... Run the speakers to their marked destination and your done. EVERYTHING NEEDS TO BE SCREWED IN TIGHT, use Oval wire clamps to make this a easier prosess. Now re-connect your battery and go to your cd player. ADJUST YOUR SETTINGS TO MAKE the best possible quality and turn it up. GOOD LUCK AND if this DIDNT AWNSER YOUR QUESTION PLEASE LET ME KNOW. Thank you and keep on asking questions

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

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.

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?

If you've got a standard 4 speaker system (2 front, 2 rear), your best option is to connect both left speakers to the left channel amp output and both right speakers to the right channel amp output. The only thing you lose is the ability to fade the speakers front to back.
