Good luck selling here. The only way I see you selling or trading these things is if you are willing to ship first and then recieve payment. Or use another member on the forum (one with good Refs and reputation) as an escrow type service. As in you ship the subwoofers to the buyer, and the buyer sends the money to the third party member and awaits confirmation from the buyer that the item arrived as described. There has been a ton of scamming go on, at this perticular forum and alot of people are picky about who they buy from.
