Just bought a new 2013 F6B last Saturday. I am running my iPhone GPS into a bluetooth helmet speaker. I have a usb thumb drive hooked up and running the music through the onboard amp and speakers. Even though the music sounds better from my iPhone and helmet speaker, I prefer to have the music through the bike so I can easily switch it off or lower the volume while keeping my iPhone GPS running.

I am not impressed with the sound quality of the onboard speakers. This is my first bike with speakers so I don't know it is the wind thats causing a problem or the speaker quality is poor. Is it worthwhile to upgrade the speakers? If so, to what? I wear a full-face helmet, so the helmet is reducing the sound as well.
