OK, I had this new Pioneer HU installed a few days ago. My question is: is there a way to know or to check if the wires from new HU are conected corectly to each speakers polarity(- +) without disasembling everything. The sound is good, but I hear that even if the speaker wires polarity is inverted, its hard to tell since the sound its pretty closed to correct connection. Just wanna make sure.

If a speakers polarity is reversed then they have poor bass response. Listen for this from each speaker(use the fade and balance controls to check one speaker at a time).

Yes, the easiest test is to isolate a pair of speakers (fronts or rears) by fading all the way, one way or the other.  Now as you balance more to one side (left or right) does the bass increase?  If so, you have a speaker wired incorrectly.  You can do the same test with the rights or lefts only, and fading front to rear to ensure all speakers are wired properly.
