Interesting subwoofer dilemma

if u were near central florida id come give it a look, but ur tooooooo far for me. lol
to check for out of phase you need to pull the sub out of the box and switch the + and - wires. basicly take the + wire and put it on the - and take the - and put it on the +. if it works, great! if not then you might have to do the same thing where he used the Left and Right rear signals to run to the amp.

IMO to check this even quicker just switch the + and - wires that are connected to the box from the outside.
