I have two JL Audio 12w6 subwoofers up for sale. I don't think I have to explain the specs on these as anyone who knows car audio knows these things hit hard. They are used, but in great condition. $225 for pair
I also have a sealed encloser for a single 12" woofer with a Lanzar Optidrive 2200 amplifier attached to it. I would sell the package for $200 or just the encloser for $30 or just the amp for $180.
I also have a set of Polk Momo MM6 component speakers for sale. They sound great with some very good clarity for the money. They are used, but also in great condition. Below are some specs on these speakers. $130 SOLD
