Aftermarket radio/CD install for '90 Miata?
I'm interested in replacing the EOM radio/cassette (2 small knobs on
lower left) in my '90 with a FM/CD combo. I also want to install a pocket in the void which will be under the new unit. Sources/Directions/Advice appreciated. Not interested in moding the existing unit. The car came w/o headrest units which I will install and place on the rear channel. Chip L |

Barry,
Incorrect about " all Miatas " came with the wiring for "head rest speakers". The "base" model came with no radio or wiring for head rest speakers. They were dealer installed if you ordered them. My '91 came with no radio or wires. Bruce Bing '03 LS |

I can't really get a balanced sound. i suspect that your wiring is crossed somehow. there's a page at 12volt.com for the wiring for 94-97 to use as a reference, though truth be told, i think they're pretty much the same as the 90-93. >I have a 96.5, so I theoretically do not have the "Jeff Anderson" problem, >but maybe I do. Never figured it out. > jeff anderson problem? and we're agreed that the seat may need to be wired (which i referred to as the wiring harness), but that wiring from the stereo to the bottom of the seat should already be there? though what i originally did was run wires from the head unit down the middle under the carpet past the stickshift, etc. and then spliced it all together under the center console. it worked. -------- "any words spelled incorrectly are probably typing errors" |

Aftermarket radio/CD install for '90 Miata?
Well as I said, my '91 did not come with a radio or wires for the seat
speakers. The plug for a radio was there, but no other wiring that came back past the dash. When I put in a radio ( non-OEM ) I had to get a plug to match and wire to the radio wires then add rear speaker wire and disconect-plugs. The Clearwater spraker kit came with wires to run down the back of the seats and I needed to add the connecting plugs. It sounds like the later Miatas came with the wireing in place.
