I recently purchased the Proclip iPad headrest mount to show videos to my young daughter. Since she is too young for headphones so I'm looking for a speakers (either bluetooth or wireless) to use with the unit. Unfortunately the built in speaker doesn't provide enough volume and at age 2 1/2 I don't think she is going to be able to deal with headphones for a few years. Thanks for any recommendations regarding third party units and how they could be mounted or placed within the car.
