How do I sync iPad to wireless speaker

If this a Bluetooth speaker, turn the speaker on.

On the iPad in the Settings App, turn Bluetooth on, wait for a list of Bluetooth devices to register on the iPad.

Select the name of your Bluetooth speaker that should show up in that list.

Bluetooth speaker and iPad pair and should say Connected when done.

Then, your audio should play through to the Bluetooth speaker.

some bluetooth speakers are required to be put in pairing / discovery mode before they can be paired with a new device if so the manual of the speaker should describe how one goes about doing so
