I just purchased this Pioneer H/U for a good deal. It's a Pioneer AVH-6800DVD. I am going to wire it up with my existing flip down monitor since the bass broke the dvd player on the roof mount one. I have just recently ripped out this show setup, i am rebuilding to a Real SPL setup. My gaol is to break 150.0 db @ the headrest, while still maintain a show quality setup and stay in the same class i compete in in M.E.C.A (street 4/ Db4).
