Hi guys! We were thinking about going to the drive-in tonight and had a question. Does the sound come from an old style speaker box or over your radio?

Some screens do have speakers closer to the screen but most you do need radio. They will tell you the channel at the gate

Radio

Depends on the screen youre at actually, but really you should plan on using your radio.

It comes over your FM radio I think it's 97.6

You can use both.
