This is my first time wiring subs and not hooking them into the head unit directly. I powered and grounded both subs(in separate boxes) from the same source. I wired the high input positive/negative left/right together from both subs and then to each rear speaker. But only the sub on the drivers side is playing. They both show green power lights and neither is in protection mode. Fuses are also good. Not sure what I could be missing and don’t have equipment to check motherboards..
