testing a drivers polarity

Only thing you can do really is to use a speaker popper and hook up its positive and negative connections to what are on your enclosure as positive and negative.  Then watch to see if the cone moves away from the magnet, or towards the magnet.  If it goes towards the magnet, then that particular pair of speaker connections is out of phase.  If it moves away from the magnet it is hooked up correctly.

Actually I forgot to ask you....are these hooked up in such a way that there is only a single speaker terminal on exterior of the box?  Or is there a separate one for each sub?

Take one penlight AAA battery and connect to sub, if it moves out then subs polarity will be same as the battery, aka you have sub + on bat + etc.

Ethan,

     They are wired directly to the amp bypassing the terminals on the enclosure.  The cable comes from the amp and is soldered to one driver and then another shorter cable runs through the divider and is soldered to the other driver.

     Is a speaker popper the same thing as what Emerald was describing? I figured that hooking them up to a dc source would reveal if they were wired out of phase, but dont want to damage anything in the process.

Thanks for the quick answers guys, I really appreciate this and finding this website.

Yea it is the same thing basically.  Some people swear by only using 1.5v batteries but i've used a 9volt and 12v many many times without any problems.  I mean obviously once you locate the proper speakers you don't want to keep on "popping" them repeatedly unless it's necessary.  I've never used a power supply to accomplish this as that not only seems like too much power going into it, but the battery is portable and just always more than sufficient for me.

Do you know if the subs are hooked up in series or in parallel?
