I'm looking for a used OEM 10" Kicker w/ amplifier combo. Part number H630SFJ301. I really like the idea of the OEM subwoofer being made for my car and out of the way in my trunk, but the only ones I've found so far are new and way overpriced. If anyone has one in decent condition and willing to sell or knows of a website where I can buy it used or discounted, please let me know. Thanks
