I dare you to use the '89 wiring diagram on a '91 with airbags.

I have an amp in the trunk where the spare tire would be in a coupe, I think she was saying she wanted to install a SUB where the tire is

I wouldn't recommend putting a subwoofer in the spare tire area even if you retained the tire because the spare tire cover will rattle like hell.

might drown out the sound of other more annoying rattles lol

Remember, I also have a Mazdaspeed Protege, so rattles and clunks are right in my comfort zone. LOL

I'd be ditching the tire if a sub goes there, I'd never put one under the tire.

Yes the stock cd player sucks, and that was from the factory. That is why I bypassed it internally and added an aux jack for my iphone. The cd player connects internally to the radio through standard computer cd audio cables. I ordered a special 3.5mm jack and installed it in the face plate on the right hand side of the stock AE processing unit that mounts under the radio. I wired the output from the cd to the jack and then from the jack i went to the cd input on the radio. When no cable is plugged in, the cd player works normally. when a cable is inserted, the audio from my phone plays. You have to leave a cd in the player, so the radio will accept input on the audio channel. It works fine on the bench, I have not gotten around to putting it back in the car. I have a spare stock radio in there at the moment.

Happen to have anymore details on this process? I have that same audio system on my workbench and it will be going back into my TII never ending project. I would love to put an auxiliary input jack in the system so I could plug in my phone/iPod. I've had the faceplate and top panel off to poke around, but it appears the correct wires are deeper in the stereo's innards.
