recently i've purchased 4 pioneer 6x9" speaker
it's rocks amazing but when i hook up them on amp in parallel i heard shitty sound
so i decided to check the polarity but i found there is nothing wrong
but when i do the speaker test with battery :
(i connected battery direct to the speaker )
2 speaker move upward and 2 speaker move downward !!!!!
i searched about this problem and i found this article on basic car audio

NOTE:
I've heard about at least one speaker manufacturer that makes their drivers with the polarity opposite of the above diagram. It is a company that makes drivers for use in commercial PA cabinets, so you won't likely see them in cars.)
so when i connect 2 speaker parallel that move downward on amp channel 1
and connect other parallel that move upward on amp channel 2
the sound is amazing!!!
so what suppose to do now?
is keep it
or
change the original polarity for the speaker move downward
and plz can i know that wrong polarity harm the speaker?
