there is some discussion on this point. Arguably, the + terminal on the amp should be connected to the + terminal on the speaker so that when a large-displacement bass note hits the speaker, the speaker cone goes outward. The other side of the argument says it's irrelevant because it depends on which side of the signal hits the speaker first (the signal is an ac waveform) and the negative side could well hit first and thus move the cone inwards, so it doesn't matter.
My personal choice is to phase the speakers so they sound the best in your car.
FWIW, I remember reading somewhere that best sound is obtained with one speaker 'out of phase' so to speak with the others. I don't remember why, it's just there. Your experience would seem to back that up.
