The stereo is all Sony. I have a sony cd/mp3 controlling the main sound and a sony 7" indash dvd player for video. I have 8 6.5" sony 2-way speakers, 2 10" 1000watt subs, and 2 15" 1200watt subs. I custom built the inclosure and plan on further adjustments and additions to the overall system. im going to add a visor monitor on the passenger side and a 15" monitor to go in a custom console for the back seat passengers.
