I'm selling a Shaker 1000 audio system from a 2006 GT. Included is the head unit, subwoofers w/ box, amplifiers w/ rack, and all speakers minus the door subwoofers.
To be honest, the only reason I priced it so low is due to the fact that I wouldn't have to deal with packing, shipping, etc with a local pickup. Saves me a lot of hassle, especially with my work schedule.
