Yea, i'd do it like above.make another front baffle, carpet it and screw it over the existing hole. some silicon should be used to make it air tight. then cut a new small hole. i dont like your odds of putting a baffle in from behind
Even if it's just like a circle baffle that's slightly larger then the subs diameter. Doesn't have to take up the whole baffle like the original.
