Minimax preamp,inverted polarity question


Greetings

I'm wondering if the sub I'm running is out of phase with my main speakers.

I have a Minimax preamp that inverts polarity,my Quicksilver Mid Mono block power amps,do not invert polarity.

So,at my speakers,I'm currently running them red on black, black on the red of the speaker.

Now, I also run a B&W powered sub,I run the sub off the Minimax pre (it has two sets of outs)

Question: is my sub in phase with my main speakers.Im running it plus to plus Neg to Neg..

It would seem maybe not,seems to sound OK............??

Should I reverse the rca at the sub?????

Comments welcome

Thanks

Everybody,thanks for the input on this..

Ok, what if I remove the woofer on the sub and switch the wires around there????

What do ya think? Would that work??

Note:
There's a Phase switch on the back, it says "0 OR 180"
I don't even know what that means..or what it does..
When I switch it, the mid bass gets bumped up,I keep it at 0
