Second, thats the protection mode - it protects the amp from shortcuts in the sub.If it turns red then it got a shortcut. See if the subs still have the 4ohm resistance and redo all wiring from amp to subs. Check all screws on the amp and the socket on the box, the wire from the socket to the sub terminals
Do you get sound on the front and rear speakers?
You can troubleshoot it by removing 1 of the sub wires. lets say to remove the +wire on the L sub, if it turns green then you know to look for shortcut in this circuit. Do the same with the + wire on R sub.
