The factory HU may have had some built in EQ to compensate for the speakers and setup of your car. You have removed that with the new HU. Rockford Fosgate, Alpine and others now have black boxes that can simulate this EQ or even make it sound better. But they aren't cheap. Also, don't use Loud or any other bass boost without knowing what it is doing to your system. Elemental Designs has a great video tutorial on what bass boost does to your system. They show how a little boost will clip your signal a lot.

Add your speakers and see how that improves the sound. An EQ and RTA session may be necessary.
