Are you talking about music INSIDE for YOU?
Or outside for customers??
I ask because the last festival I was it --- when we had summer --
It seemed like every darn truck had fricken music blaring OUTSIDE the truck.
Some of them have speakers mounted outside.
Some have a big portable PA speaker.
I get it if you are the only truck on the street.
And you want a LITTLE background music going outside.
But these idiots seemed to all be trying to out do each other.
They were all lined up back to back to back.
Couldn't even hear the ACTUAL festival's live music.
That said... I too grabbed one of those portable PA speakers.
I think I got this model.
I can use it inside the truck for music.
SD card slot, bluetooth to phone, fm radio. 60 hours of battery life.
But I also got it because at the festivals, they were also using them to call out order numbers for pickup.
THAT part was a good idea.
So that's MY plan for it.
Also ordered a wireless headset / mic to pair with it.
Other than that I have a Ryobi radio
Runs off the batteries, and off 110 v plug in.
Radio, bluetooth, plug in mp3 player.
It works not too bad.
Not a party box, but just fine for inside the truck.
