Getting a new Head Unit system. Im looking for the absolute best sound quality possible for under $300. Whether it be a stand alone Head Unit or a Head Unit and external EQ set up. So far ive read up on the Pioneer DEH-80PRS which is spoken highly of but could use some advice on what else to look at. I have 2 Infinity Kappa 4', 2 Infinity Kappa 5 1/4' and 2 Kappa 1' Tweets with 2 Rockford Fosgate DVC shallows. Looking purely for the most potential audio quality and control, id like a sizeable EQ whether it be external or built into the deck.
