2007 Pontiac G6 Memphis 15" Subs hitting backwards (******* in)

[mike_d]

I have an 07 Pontiac G6 GT. It has the factory monsoon amp still running all the door speakers and the 6x9s. I have 2 Memphis C3 15's hooked to a Hifonics Zeus 1800 amp hooked to the factory head unit. I am tapped off the factory sub wire and it pulls the speakers in instead of blowing them outwards. So I thought maybe the factory amp is interfering with it so I tapped into the rear channel wires before they hook into the amp and the subs still pull in. I took the subs out to make sure they were wired correctly and they are. I'm stumped at this point and would really like some help. Thanks!

Isn't that a polarity issue? Like you have the negative connected to the positive, and so on?

is there a phase setting on the amp?

could be set at 180 instead of 0

Which is the same as switching the +/- sub wires.
