This is a common problem. There are several capacitors on the power supply and logic board that are bad. Replacement of these parts has restore all units that I have looked at.
On the power supply I would replace at a minimum:
C14 - 4.7ufd 50v UPW1H4R7MDD
C4 - 1ufd 50v UPW1H010MDD
C8 - 100ufd 25v UHE1E101MED
C10 - 470ufd 16v UHE1C471MPD
C12 - 1000ufd 10v UHE1A102MPD

There are 4 others in the supply that were not grossly bad.
C1 - 22ufd 400v EEU-EE2G220
C7 - 220ufd 25v UHE1E221MPD
C11 - Same as C10
C13 - Same as C10

Logic board:
E5 - 33uf 35v EEU-FM1A471
E6 - Same as E5

Part Numbers of replacement caps are Nichicon or Panasonic.

Note: Caps on the logic board are extremely hard to replace due to the internal ground plane.

Contact me if this is beyond your skills for possible repair.

Hey i dont know to much about amps, but me and my friend (he knows a decent amount about amps) would plug the power into the amp and the green light would come on. Though when we plug it into the subs, the...

Are you connecting positive to positive and negative to negative from the sub to the amp? If so, try positive to positve (+) in the far left channel and then the negative to negative (-) on the far left channel to. If no luck do the same in the other channel with one sub at a time. Try one sub at a time, Dont try an connect 2 or more subs to one channel as this would cause the amp to go into protect mode (red light you describe). Usually the positive wire has either a line down the wire, writting on it or has a red seperate wire with it when wire end stripped to connect it. Hope this helps and please rate...

read the owners hand book
normally the lights stay red until the battery is charged then it goes green
if the power is cut or if you switch the point off with the charger still in it and do not remove the charged battery , the battery will discharge through the charger
