ARC AUDIO MOTO 600.4 4 CHANNEL 600W RMS CLASS D AMPLIFIER WITH MOUNTING BRACKET THAT FIT UP TO 2013 ROAD GLIDE. I HAD THE AMP MOUNTED ON MY 2008. IT MOUNTS TO THE TURN SIGNAL SCREWS ON INSIDE OF THE FAIRING. UNIT WORK FLAWLESSLY WHEN I TOOK IT OFF THE BIKE. CURRENT BIKE ALREADY HAD THE ROCKFORD FOSGATE AMP SET UP SO I DID NOT FEEL LIKE TEARING IT OUT OF THERE TO INSTALL THIS AMP. DON'T MISS OUT ON A GREAT AMP FOR A GOOD PRICE. $275 + FREE SHIPPING TO CONUS!!!!!
