Hi all, I'm new! My name is Francesco, from Italy Two questions: 1. Where I can find U.S. Amps IS2150 Manual? 2. Today I tested it but there's a little problem... If I put signal on right input channel I find speaker output on left channel and viceversa! The board is REV. A. Is possible that the IN-OUT RCA serigraphy is wrong? (Normally RED is right and WHITE is left...) I also find some distorsion on both channel but i'm not fully sure because I used only a 200mm woofer. Power cable in photo is just to test it..if it works I give it a 2AWG Some photos: I hope you can help me, thanks in advance!!
