yup, just what i thought, all that wind noise will just drone out the audio. oh well we can always enjoy the great sound coming out of the exhaust pipes of our 700's just need to invest into an aftermarket exhaust setup instead of audioThis topic was already been discussed. Those are not speakers, just simply covers.You can try to make it work but the wind noise would be too much of an affect to the idea.
You apparently haven't heard Harleys going by. They have the speakers blasting so you can hear them about a mile away, loud enough to drown out their illegal loud pipes.It's going to be pretty hard to hear that radio when riding. The only time you could probably hear it is when stopping at redlights. Best to just get earplugs.
