Amp not working at all...need schematics

I have an American Legacy Series 2 1600 watt amp. MOdel number LA1490. It was given to us by a friend, becuase it doesn't work at all. We opened it up, and fixed a thing or two that was obviously broken, but....it still doens't work. It looks like maybe there may be a broken solder connection, but I need to get ahold of the schematics of the inside to see if the connection really is broken. Anyone know a source for that? Thanks!

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.

Whats rms on legacy la1490

http://en.wikipedia.org/wiki/Root_mean_square
In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.
However, the term "RMS power" is sometimes used in the audio industry as a synonym for "mean power" or "average power". For a discussion of audio power measurements and their shortcomings, see Audio power.

Subs

I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.

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.
