Wiring polarity
I have a new system all wired up, but I'm still waiting on the deck to get the whole thing up and running...
When I wired the speakers to the amps tonight I got this hunch that I might have the polarity wrong AT THE SPEAKER...(the reason for this is the wire had to be flipped at the amp to get the color coded side to line up with the negative terminal...I thought I made sure that color coded was always negative, for speaker wiring purposes...)
Short of taking apart everything I've done so far, is there a cheap.easy way of checking to see whether I have reversed polarity?
Thanks

FYI the color coding line on speaker wire is called a 'trace'.
If your polarity is in correct your low freqs will not reproduce correctly. From experience as long as all of your polarities remane constant you would hard pressed to know they are wrong. But if they are not constant you would know pretty fast by the abscence of low freqs (they would be canceled out)

If you go to this page and scroll down half a bit you will see a link to a polarity pdf file. This may help you out since it sounds like you are splicing into the factory wiring.

You can also get a D cell battery and connect (by hand) the + and - to one one end of the cable, the other end goes to the SPEAKER + and - teminals, the "correct" polarity would push the speaker up, reversed polarity would pull the speaker down.
Experiment and you might find that the sub might actually sound better when fired out of phase (reversed polarity), compared to the other speakers in the car. Some head units (like Eclipse) can also switch the polarity automatically as well
Good Luck!
