I assume that by "speakers" you mean "subwoofers". The only time you play subwoofers out of phase is when they are mounted in an inverted style. That is, when they are mounted with the basket outside of the box and the cone pointed towards the inside. Thats the only reason I know of, maybe there are others.

For a listening environment phase is relative.
First, just because you hooked + to + and - to - for all the speakers in the vehicle they may not all respond in phase. Miss labeled, different types of speaker or mounting (as noted above) can cause this.
Let say you have + to + and - to - and all the speakers respond in phase with one another, you may still have your mike (SPL vehicle) or listener (SQ vehicle) in an out of phase position or node (point where sound is cancelling).
Phasing can effect both tonality and staging. For an SQ car I normal set phase for best stage and image and use the EQ to correct tonality. Sometimes an EQ will not fix phase issues and you will simple need better speaker locations and go throught the process all aver again.
In an SPL vehicle phase for what's louder.

i've been told that if you run multiple woofers off of one amp...ie, three w6's in a 4ohm load on one single amp, then you may have a phasing problem due to the signal getting to the first woofer, first. It seems to hold some logic, but never tested that theory. does that hold some truth?
