Input:
Read about these on Miata.net for use in headrests.

YES, they sound better than a pair of ripped rectangular paper speakers in your Miata's headrest.  But anything would.

They don't put out much sound, and the sound you get is not very clean.  I can't recommend them.  Get real 3.5inch speakers.
