The first unit I put into the car  had good looks, didn't need to take off the face but delivered fake bass and the graphs were a bit tacky and also invisible during day top down
The Pioneer was great at differentiating bass, mids, and high's but could not deliver high quality mids. You also had to take the face with you
This was a revelation but it wouldn't fit the dash as advertised and because of my car having no silver dash it would pop out ugly. The CD would also jump alot
This unit was inferior than the above, but it was easier to use and had better clarity of sound. Unluckily It was awfull during the night because of ...Korean display
This unit was older than the rest, had no sub-out but magically delivered the best sound without trouble even at the highest vol. level! Amazing, mid's and bass
