I have 2 12 Kicker COMP.Ds with a custom made ported GE box. And 2 CD players, a JVC color changing one and a Pioneer with hookups. Subs were bought last month and the box as well. Subs were around almost $300 and the box was $175. All in great shape and it all works They sound awesome and they kick hard Im looking to trade for a XBOX 360 or a PS3 or $150 cash.
