I had my stereo installer put Eclipse 4 inch coaxials in the front with excellent soundstaging. Currently, I have 4 inch Infinity RS speakers in the rear deck with a custom 12 inch Soundstream SS-12 in a rear free air enclosure. I had the first aid kit removed. My plans are to replace the sun damaged rear parcel cover and perhaps have 5.25 or even 6.5 Eclipse coaxials or even separates installed. My car is rated for 250 watts of power with a Precision Power 200 watt 4 channel amp and an Orion HCCA-25 for the sub mounted on an amp rack in the trunk. If anyone wants to see, I have some pics.

You sure you want coaxials or components on the rear shelf? It'll really really hurt your soundstage! If you desperately want rear fill, I'd go for just a midrange driver, and cross it over at about 200hz and 1khz. If it plays too high, it'll drag your carefully constructed soundstage right to the back of the car. Remember, high frequencies are directional, and you brain can tell where they are, low frequencies are not. I'd definately try it before you buy.

If you want to be more fancy, you could contruct a Hafler circuit to provide ambience (difference in left and right) This is done by putting a speaker across the positive terminals of the left and right channel, to give you the difference between them, this is essentially what Dolby Prologic does. The effect is pretty convincing if done well.

My experience with a Hafler circuit in my home system was less than stellar. The novelty wears off quickly. It's kind of a fake surround effect; I think that digital DSP would be more fun to play with, although more expensive and perhaps not very accurate sonically.

The car has the worst speaker choices I have ever seen. The sound system in my 1997 Toyota Tacoma X-cab pickup uses 6.5's all around. I know the car was built in the mid 80's and sound wasn't a big factor back then. Does anyone know if later model 190's offered better options regarding speaker locations, perhaps door mounted?

I read somewhere that if you mount speakers in the kick panels you get the best soundstage, because they are more equidistant from the listener than either dash or door mounted speakers, with door mount being the worst. (One next to your shoulder, the other behind your passenger's shoulder, or thigh even.) I'd be tempted more by an ear level tweeter in the front. The rear speakers to me are usually helpful only for bass fill anyway. Too many sources of midrange and treble can lead to phase cancellations and a lumpy frequency response.
If I were to start from scratch, I'd try (big) component woofers in the rear, component mids in the kick panels, and tweeters in the front dash, set it flat and just crank it. I'd be tempted also to use really good woofers, and a lot of power.
