I did something like this a while back, its quite simple.

- Get a TV,
- Get an old PA
- open the TV and diconnect the coils from the PCB (one 4 prong connector
usually).
- meter the wires and find which are the two sets of coils (somewhere
between 4 and 8 ohms normally)
- Connect the speaker out of your PA to these pairs of coils.
- apply you signals to the input of your PA, switch on the TV and you're
done!
