Pair of Alpine SXE-1025S 4" speakers, 2-way Coaxial system, 4 Ohm. Ideal upgrade replacement for the standard headrest speakers in an MX-5 or Roadster mk1. They are bigger than the originals but can be squeezed into the holes and then held in place when the headrest cover is zipped up. I have a pair of these in the drivers seat of my car.
NA00025.
