it says OBO in the price column and the price is a shipped price..that means throw me some offers but like everything there is a bottom line. i did pay 320 for the amp w/no bass knob or remote wire, no top plate and the plastic face around the adjustments was broken in half. I called up RF and they won't ship anything less than $50, so i bought a bass knob cable, new platic face plate and top cover, oh yeah, and a new RJ45 connector cuz the one to plug the bass knob cable into was broken, so i paid over $50 for that stuff, plus another $20 for the bass knob from a local RF dealer and $20 to have the new remote bass plug installed...thanks for the heads up
