Selling my very mint condition RD Audio D9. I bought it brand new last year and it has been flawless. Very powerful and really comes alive below 1 ohm. I have had this amp mounted on 1/4" thick neoprene foam with rubber washers above and below the mounting tabs for very good vibration resistance from day 1 of owning it. It was also mounted below my cargo floor on a 3/4" thick birch amp rack that was bolted to the truck about 12 inches from a group 65 battery with dual 1/0 power and ground leads so it was never starved for current or voltage. Basically I'm saying that I have treated it like my baby and whoever buys this will get a very nice amp.
I also have the original box, manual, and never used bass knob/cable.
