Looking for reviews on Harley audio boom system?

I was thinking about putting a windshield mounted Harley audio boom system on my Heritage. Has any used this and how does it sound ? especially going down the highway.

Why would you want to use a sound system placed into a motorcycle? It is inefficient and a nuisance, people standing around the bike will hear it better than you.
Get smart, use a helmet sound system, it is much more efficient and you will actually be able to hear the music, plus you can use it to answer phone calls and as an intercom for a passenger. Any system on a bike isn't going to do those things.
