I'm trying to find out what the speaker size is..and how can I add a subwoofer when the sound comes out of the usb port....level 1 2012 has no audio output connection under left hand compartment

I upgraded the front to db651s and the rear to db501 Polk setup. Very pleased with the sound. The DB651S takes some tweaking but will fit. AND NO I did not hack the bike to get them in. Simply notched speaker slightly with drum sander to clear speedo and the fairing support.:ssshh:
