I am selling a Phoenix Gold xs2500 on ebay right now. The amp retails in Seattle (my hometown) for $499, and can be found numerous places online for around 400. The amp puts out 500 watts bridged @ 4ohms, and 1000 bridged @ 2 ohms. I had it running 2 rf 12" dvc's for a little while and it sounded great! I just don't think my carputer can handle the rattling. The item # is : 1255503447
