What is your music source? If it's an iPod then you will get much better sound quality by using a USB cable rather than the aux input. This is because it sends a digital signal so it's impossible for information to be lost between the source and the head unit. Even bluetooth should be better than aux since it also is a digital signal.

If you want good SQ, then find a head unit that has 4 volt preouts.
