I believe parrallel is best, because they have a super high impedence so it doesn't hurt your amplifier like normal drivers.

Some heldful reference from CTS...good read about Piezo's

Depending on the amp's max output voltage, a series-parallel connection might also be recommended.

One question: Are these the only drivers connected to this amp or will there be woofers or mids as well ?

Regards

Hi,
Do not forget to put a series resistor on each piezo. Dunno exactly
what value but somewhere between 10-50 Ohm should be OK.

If you make a high pass with the piezos just connect a 4, 8 or 16 Ohm
resistor in parallel with your series R piezo setup. Then calculate the
high pass as usual for the parallel resistor (4, 8 or 16 Ohm).

Regards / Mattias

Some amps will not like the "pure piezo" as a load. The remedy has already been mentioned by Matthias: Series resistors.
