Nice setup, A good sub will take any audio system to the next level (properly integrated, of course). Sound deadening in the doors will make the biggest diffrence in the VX acoustically.. I used two Cascade door kits and a speaker kit per door and then sprayed the interior door plastic panel with a can of quiet kote per door. Closing the door now sounds like a bank vault closing and you really have to watch how hard you close the door. Then if you want to go nuts, you can do the whole rear of the truck (most importantly the rear wheel wells). I really like the vinyl based stuff (cascade) better than asphalt (dynamat), it weighs less and doesn't stink.![]()
