I went with a single DIN Pioneer Premier and love it. I did that before I upgraded the speakers and it made a LARGE difference in the quality of sound, even with the factory speakers. After replacing the speakers as well I am very pleased with the sound.
Now if JL would just do 50% off that sub for the DC I would be in good shape......
