Flash or no flash?? 2015 CVO Road Glide Ultra, my factory fairiing mounted amp let it's smoke out. Intent is to replace amp and speakers with aftermarket so my first order of business was talking with BikeTronics about their breakout harness/line leveler setup to get me started on the wiring to an amp. Donna made mention that because the stock CVO head unit has such a flat frequency response built into it's flash, that they recommend getting the head unit flashed back to a standard Ultra configuration. Anyone have experience with this? Keep in mind that I'm not much of an audio nut job, so if it makes loud noise out of all 4 speakers I'm pretty happy.
