The speakers sound great up to about 55 mph. I can listen to the music up to around 70-75, but then wind noise starts to interfere some. A lot depends on direction. The radio will go loud enough, but above 28 distortion sets in. Not sure if it's distorting at loud volume due to the lack of radio power, or the speakers.
If I had the cash Id go fairing with 6x9's. If that seems a bit much, the speaker upgrade is a good idea. Regardless, these sound much better than the Shark speakers. I can get the bass I was missing, with crisp sound at a higher volume.
