I have had some sort of speakers on every bike I have had and these are some pretty good speakers. I run it on 15 and use my phone for the music via Bluetooth to the bike and haven't had a bit of a problem hearing it even at interstate speed. I do think I will get the j&m speakers when they are available to see if that brings it up a notch. I may see about adding on rear speakers when I can find a plug and play set
