Reddit reviews Clarion Mobile Electronics CZ302 Bluetooth CD/USB/MP3/WMA Receiver

Audio is subjective to everyone. The Z is very space-limiting in terms of audio unless you want to lose a chunk of trunk to a subwoofer. I can't speak for others, but this is what my setup will be (I have all hte parts, they're just not in)

• Front speaker panel kit. Don't cut holes in anything, install this along with your choice of decent 2 way low profile 5.25" diameter speakers. You can also get the retrosound bundle which comes with low profile speakers @ 40 watts rms each.
  
• For the rear I am using the MSA speaker panel that holds 2 6x9 speakers. Mine are old JBL 3-ways I've had lying around for a while. It replaces your rear tail light panel.
  
• I haven't settled on a deck. Ideally I want a single DIN android-based unit that uses my phone for maps, bluetooth, can handle a backup camera, etc. Something like this
  
• Alternatively I've always had decent experience with Clarion, so I may just get a plain single DIN stereo with bluetooth and apps for under $100
  
• and a 4 channel amp capable of 50 watts rms per channel. Something that is relatively compact, like this Alpine.
  
  I'm omitting a subwoofer because of space and extra weight. The Z is also not a very quiet car unless you dynamat the crap out of it, and even then it's nowhere near a modern car in terms of blocking out noise. So lots of the lows will be eaten up by tire/road noise.
  

Personally I'd spend a few more bucks and do this:

• Clarion Mobile Electronics CZ CD/MP3/WMA Receiver : http://amzn.com/B006WVX9R2
  
• Rockford Fosgate Prime Full Range 3-Way Coaxial Speaker - Set of 2: http://amzn.com/B00BF6HVGY
  
  I just figure if you're pulling your stock head unit out you might as well have bluetooth and other modern functions in it.
  
  Heck, you'll probably see a good change in sound just switching the speakers out. If they are the stock speakers in there they are cheap 16 year old cones. To make the speaker install a snap, just use these:

This radio has everything you asked for and then some with nice features here and there. I haven't had the time to play with too much since it went in my brother's car but it really made the stock speakers sound better and works like a charm.
