My TV is wall mounted to the out side wall of the closet. All my components are in that closet. I wanted to place my subwoofer in the closet by cutting the wall of the closet under the TV facing my listening position.
My subwoofer is a front firing and it has two holes(not sure about the technical term) in the back.

Questions :
1. Do I need to cut the wall exactly same size of my subwoofer and make it look like another speaker?
2. Do I need to make a hole more than the size of the subwoofer about 6 inches all sides make it look like a small cabinet in the wall and place the subwoofer in there?

Hope you are understanding what I am trying to explain.

Any other suggestions would be greatly appreciated.

Don't cut the whole exactly the same size; this will constitute an "interference fit" and you'll need something like a 14lb sledge to make it fit. Cut the whole slightly larger. However, with this solution you are likely to be compromising the effect of the rear ports, an effect you can simulate by temporarily bunging them up.

I would suggest you try this first; the empirical data thus gleaned should then help you decide your preferred course of action.

I would try it in different places in the room, before making a hole in the wall!!!

To add, you might try blocking just one port (that's the term for the 'holes'), as well as both, just to see what the effect is. You might also try turning the sub around so the ports are in the room.

You may find that just making an opening between the closet and the room is enough, without the sub poking into the hole. A simple HVAC return wall grill can cover the opening and look original.

When creating the opening, you should line the hole with 2x4 and jamb between the drywall edges (where your hole is not already against an existing stud), so the wall cavity doesn't affect the sound.

The bottom line is that you should experiment. We all know that cutting holes in walls is not a simple thing, but one piece of advice: it's easier to make a hole larger than it is to make it smaller.

Oh yes!
