I am wondering how to ground my aftermarket stereo to the chassis on my 1988 rx-7

Look under the dash anywhere in that area where you have the stereo installed...there will be at least one black wire with a "C" end that is simply screwed into some metal under there that is not part of the ECU or any computer-driven controller...that is always a great ground.

Is there a better place, 2ndgen guru guys? A specific place for his kind of car isn't something I know, this is just one of my general tricks when installing aftermarket stereos in any vehicle.

Where there's metal, there's a potential grounding point. Pick the spot you like or find the original ground wire.

There should be a large screw directly behind the stock stereo with a flat mesh wire attached. Remove that wire & attach the stereo ground. If not you can use one of the lower stereo mounting holes, the top 2 screw into plastic but the lower 2 screw into metal behind the plastic & will ground the radio without alternator noise, simply attach the ground wire to a screw & screw it in. The shorter the ground wire the better.
