Would probably be helpful to give us a lot more info. What bike? Aftermarket stereo or OEM (i.e., Vaquero/Voyager, or an aftermarket handlebar mounted setup on another bike?) Which slip-ons? Another thing that might be helpful is to post your question in the bike specific forums (1600 if it's a 1600, 1700 if it's a 1700, etc.). Good luck!
