I have a kenwood sigma servo home theatre sub, the sub has only one coil, but I think that it reads the current like a PT does, and can deduce the coils movement from that, in a car audio environment, however all bets are off.

 

the sigma uses the same coil that you drive
you can hitch it up by running a smaller guage wire to the terminals
or you can just jump the speaker output terminals to the sigma input terminals

^jumping it to the terminals apparantly doesnt work as well, not that ive ever noticed a difference between using the servo, and not using it...

 

case in point its not the servo thingy that was messing up the sound from my amp, apparently its bunged up.

that and i blew up the kenwood sub on my way to work earlyer this week, whoops
