This cd-unit is really a great buy. The amp cranks out plenty of power and the deck is LOADED with features, one of the greatest being the programmable EQ. You can tweak the sound beyond your imagination, and the sub-out makes this an even greater buy. I especially like the Front Image Enhancer feature which allows you to direct the low-frequency sound out of your back speakers which enhances the sound quality greatly because they act sort of like subs. If you are having a hard time choosing between decks, you should look no further and go with PREMIER by PIONEER.
