I put rear speakers in my ES the DIY way described elsewhere on this site. Having done that, I would highly recommend buying the speakers from Mitsubishi. They snap into place and are the correct impedance (meaning the volume from the fronts and rears will be the same). IIRC, the speakers were not cheap -- $90 each -- but the convenience and correct fit/impedance is worth it.danpatgal said:We just wanted to put in rear speakers (so our kids can hear the music too) ... seems like that should be a no-brainer, the wires are probably there (haven't looked yet), just have to find the right size speaker.
