I ordered a shark system from
www.gooddeals18.com.
I enjoy it! I can hear my music at speeds of 80mph indicated.
I do have a givi tall screen, however still cut just below my eyes.
I can hear it fine. i don't have time to tak epics right now but if you want me to just say so.
BTW its a 100watt system under the seat. no problems to date (except speaker brackets which i can lead you to the right way)
I ride my KYMCO just for the lone reason i can listen to my music on it, however, then i remember how quiet it is.
