Answer
Hell Christian,
One of two problems I can think of to start. 1-the balance control may be on one side? 2-the speaker wire for the side that doesn't work may have been accidently grounded which burned up the amp IC for that side? On a high powered stereo the speaker wires cannot be grounded to the chassis or the amp IC's will quickly burn up! also the + and -'s cannot be connected together or the same will occur. Double check all the connections for tightness.
