I have an Audiopipe AQX-1800d in GREAT condition. I paid 226 and they go for over 250 on eBay but you can get it for 175+ shipping to your door. It will ship in the original box with both the bass knob and knob cable. It has a tiny scuff on the silver pipe on the top of the amp but is flawless other than that. It's the best amp I've ever owned and withstood the hottest summer in Central Texas history without protecting once. It beat the hell out of my Sundown SA-12's. Pics of the scuff Bass Knob Everything
