i have an aftermarket cd player for my 93 touring. how can i install it without rewiring the whole car stereo? is a non-bose rx7 wiring harness the same as my bose harness?..

you should be able to get a radio harness at any stereo store but if you are going to put all new speakers then you have to rewire you dont want to use the stock wires coming from the bose amps it is a pain in the ass do it right the first time

You can install the aftermarket cd player and use the stock config, but it's complicated, you would be better off waiting until you can swap out all of the components of the system, aftermarket amps, drivers, upgraded wiring, etc.
