If the speakers are out of phase, you will get very thin sound
with virtually no bass output. If in doubt, reverse the wires on 1 speaker only
& see which way sounds better.
A speaker with a larger magnet is
generally a higher performing speaker. It will take a bit more power to drive it
then the one with the smaller magnet.

Polarity/Impedance 4,6,8,ohms
The polarity isn't critical, but the speakers should be "in
phase" to function properly. That means that they are hooked up the same way.
When they are out of phase, one speaker will vibrate the opposite of the
other. An easy way to test this is to hook it up one way, turn up the base, if
the base comes out the back, it is backwards. Both speakers should be
connected in such a way that the base tone emanates out the front of the
speaker.
If the original speakers didn't have different connectors for
plus and minus, or if they are not colored or labeled, it really shouldn't
matter, but I generally check it anyway.
If your radio is designed for
an 8 ohm speaker and you install a 4 ohm speaker you WILL damage your radio.
It is absolutely critical that you install the correct impedance speaker for
the radio in your car. If your radio is designed for a 4 ohm speaker and you
install an 8 ohm speaker, the radio will not be damaged, but the sound quality
will suffer.
