I've got a 4x4 box that Im building. Im running a four inch exhaust up high and two 4 inch passive intakes down low and needed ides on light proofing the 2 lower 4 inch holes. The simpler the better. Any ideas or suggestions are always appreciated.
Post # 9 in the thread that desert joe put up is a good diagram of the staggered 2 x 4 's idea that GC73LPC suggested . its how i've got my intake for light proofing & it works well .
mine is a homemade box framed out like a room . so i just took one bay on the side wall staggered 2x 4's down the bay so that my intake on the outside of the box is mid way up the wall & inside the box the vent is on the bottom . so the air comes in from the upper vent ...passes through the 2x 4's down the bay & out the bottom vent in the cabinet .
