Do they have speakers outside the vehicles or can you only tune in though the radio?

I saw speakers on the lawn area, but I used my radio from vehicle.

Screen one has speakers on poles near the parking spots in some areas, however they are not loud at all. I tried to use them because the truck next to me was turned on for heat and it was so loud i couldn't hear the movie. On nice days sitting up close to the screen is nice and there are large speakers there for both screens.

They have speakers in the first 3 Rows closest to the screen behind that you must use your radio

No speakers that i could see. Only tuning through the radio. Plus they have large speakers outside to either side of the screens which is nice if you like to sit outside your vehicle
