Speaker 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.
