I found the small ceiling speakers were pretty useless once we were driving down the road. I had to have the radio so loud to hear it, I was driving my wife crazy. When our Jensen radio with the slide out screen died, I took the opportunity to upgrade the radio to a regular car stereo and I added a separate monitor for the rear/side cameras. I also added some powerful satellite speakers to the bottom of the cabinets, just above our heads. The sound is great, don't have to have it too loud and I added a speaker switch for when we're parked, I can go back to the original speakers.
