I just installed a pair of Kappa 62.11i in my '15 and while sitting in the garage you can't turn them all the way up without your ears bleeding. I went for a quick ride and the volume is gone, the stock speakers were louder. I have turned off the AVC and also tried it at different levels with no success while riding. I just had the bike serviced and the dealer installed the firmware update as well. I am not running an amp yet but from all the post I have read on the Infinity Kappa speakers just installing them alone would/should help with the sound. If anyone has had this issue or knows how to remedy the small sound while riding I could use some help.
