I also then added some intakes. I am using 2 6: staigh ducts. inside pained flat black and both have fantech 6" dampers. They vent in from the right side of the cab . There will be a vent painted to match the cabinet that is only 1 inch deep. Looks like the vents you see on clothes cabinets. Under the vent is a filter to stop uglies from entering the cab.
