Currently have a red 09 nissan rogue and looking to add a car audio system with navigation screen, speakers, and subwoofer. Looking to do it pretty nice, so i have a budget for around 750. Too little to do it too nice? Also i am not sure where to start but i like to bump and i want the sound sounding clear. Not sure where to start with company's products or what, and how much is installation etc? Any has any help here that would be nice.
