Are these 4"??? I dont know the depth? It would be nice to know this as well because I just ordered a Focal 4ch amp so I have to fill the rears now otherwise I will have to bridge the amp. Do you plan on going coax or just a mid or maybe even a comp?

I agree with you, Rear fill really does add alot of ambiance that would otherwise be missing.

I will tell you, you are not going to be able to fit 4" without alot of modification. Find a good set of 3-1/2" speakers and cross them as high as you can. At least 150 to 200Hz and 300Hz or 400Hz would be even better as you can apply more power to them.

I used a set of JL Audio CS series and they fit perfectly. I wanted to put a set of 4" focal polykevlar midrange speakers in there but they wouldnt fit. Depth does not seem to be an issue with speakers this size.

I wouldn't bother with a comp set. A good coaxial or just a midrange speaker will suffice for the proper effect. You are not going to hear bass or highs from them anyway.

So the JL's you used are 3.5" and fit the rears? These would be perfect for me.

Pls advise so I can order today. Thanks

Yes, I used the JL Audio C2-350x Coaxials.

I have Dynaudio components which I believe are awesome for the Z. I also built two boxes of subs that fit behind the seats.

People are correct about just having highend fronts....after a while you can't tell the difference. In my case what I am trying to eliminate is the noticeable non-existence of the rear speakers the first 5 minutes of getting into the car.
