Yes there are three Din pockets. The radio occupies the top. In the middle is a pocket with a door and on the bottom is an open pocket. You could essentially order the double din cassette deck HU with the extra six disc changer all in the dash. Or you could get the stock HU, 6 disc changer and add a gauage pod. On the Baja classic the drivers seat is power and the factory sub is under the other seat. Doesn't leave much room for an aftermarket amp. Does anyone else have any upgrades on their audio system and if so, what have you done?
