I have a friend that needs to sell his sub/amp/box ASAP. Just blew his engine in his Civic SI so he needs money like now. Selling an Infinity Perfect 12" subwoofer with a box made out of 3/4" MDF built to Infinity's specs and covered in dard grey trunkliner material and an MTX Thunder8302 amp to go along with it. Looking to get $275 + shipping for all or $250 + shipping for just sub and amp. Help me out here...this is a great deal on a great sounding setup.
