Hello with tax season around the corner I'm looking to upgrade system, I'm looking to buy two x-12's and a ported box to match. Won't be a quick buy because I'm waiting for taxes, but thought I'd post this now incase someone is looking to upgrade their ride, looking for something used but not trashed, please don't ask "what amps are you planning on running" or any similar questions, it's none of you business. Just looking to buy some subs. Please include shipping price as well. Hope to hear from someone!
