I have a used JLW7 12 Single 3 Ohm coil that is in good shape has about 6 months play time on it. Sub is 100 Percentno problems what so ever. I am looking to trade for either 2 12's or 3 10's some thing along the lines of POWERBASS EXTREMES or KICKER L5's maybe some ALPINE TYPE R's or low level ATOMIC subs. I would prefer them to be new but will take used. I will try to post pics tommrow. Let me know what you have.
