Headrest Speaker, Mazda MX-5 mk1, new replacement

New Visaton replacement headrest speaker, 8 Ohm.  Sold individually.   2 required per seat.  Aftermarket replacement for the standard headrest speakers in an MX-5 or Eunos Roadster mk1.  Note that the magnet on the back of these is bigger than on the originals, so they do not fit in the plastic boxes that the originals were in unless you cut slots in the box, this doesn't matter in practice as they fit nicely in the holes left by the old ones,
