Subs w/magnet out, Reverse Polarity?

When you mount subs with the magnet outside box, do you reverse the speaker wires? Or using the phase output reverse in head unit is the same thing as switching speaker wire polarity, right?

You still need to reverse the polarity in any situation where the sub is in reverse, , never rely on the deck to do the phase reversal, ,  what if you disconnect your battery and it resets, , then your subs blow??    You must reverse the wire's at the amp.

Basically, when you hook up a sub normally mounted into a box, and wire it normally  it sounds great, , the signals are amplified with the intention to fire outwards away from the sub, , but if you reverse the polarity and keep the sub normally mounted, , then the signal is sent to the back of the sub, , meaning the sub is fireing backwards, INTO the box.  Usually the sub compresses the air outside of the box, , but if you have it wired wrong, you will have the pressure inside the box, ,the sub will struggle, and over heat.  The bass will be noticeably quieter, ,and you will be able to hear a humming.

So basically it all comes down to what way the sub moves to make its frequencie, ,+ to+ the sub moves outwards, , + to -  the sub moves inwards.

I was just having fun/experimenting while I am overhauling my trunk/system, so I mounted my 8000's upside down on my new enclosure to see what it sounded like. SO, I will switch the wires and adjust my phase output back to normal as suggested.

BTW, it sounds lovely that way.

I always thought that when a sub hit, it was moving inward, pressurizing the inside of box. So it's actually moving outward and pressurizing the outside air?
