Internal Communication System

Anyone running an ICS in their Jeep? Love running with no top or door, keep the rear on because of my daughter. Which is why I am looking at something that would allow me to talk to her while were going down the road and still allow for music. Did some google searches and all I come up with is Rugged Radio has a system that looks pretty good, but I would like to get some more options and opinions. Thanks.

If I have someone in the back seat I just yell really loud at them. Other then that I can talk just a little louder then regular to the person sitting next to me with no top and no doors on.
