I have a rockford fosgate p250.2(2 channel) and a rockford 600.1bd(mono)they are in mint condition. I only bought them in august and used them til the beginning of october. Have original box and manuals. Will also throw in a bass knob. if interested gimme your email so I can send pics.
I dont know if they will work because the sub amp works best at 2 ohms, but I have a 06 zx750.1 (939 watts on birthsheet), and 06 zx350.4 (354 watts on birthsheet). Both mint condition boxes, manuals all. Just getting ready to ebay them but 250 + shipping for both.
