I've got my old sub lying around, it's a 10" sony in a truck box (nice and slim if you wanna keep your trunk...) and the Profile amp I was using to drive it. Amp does 350 watts RMS at 2 ohm, 220 at 4. Not anything to write home about, but it does add some nice lows.
I'll bring it to the meet, $100 or best reasonable offer takes it.
