Up for sale is a used JL500/1. Got it off a friend for doing an install and I really have no use for it. It has some very slight imperfections from normal use (nothing really noticeable unless you are really looking for them). Does 500 watts rms from 1.5-4 ohms and from 11.5-14.4 volts. Looking for $275. (Not really looking for trades at the moment).
