i was so happy cuz i just finished and everything worked for a few minutes, lol. i partially pulled out my soundstream xta480.4 to do the gain adjustments and i heard like a static like sound and no highs or mids. the volume was at about %75 so i could adjust at a decent volume. my bass amp and subs are working just no mids and highs. the green light is on for the amp so the amp is on..........
