Jeep Build Help

Hello,

I currently have a 04 jeep wrangler unlimited, now i created an ok fiberglass enclosure with the help of my father, yet he just happened to drill holed threw the box where the sub sits so now it sound terrible, my subwoofer is the alpine swr-1042d, my question is if anyone would know how to make my sub sound better and not have it push air threw the holes since the box is so post to be sealed, and what requirements would i need for a simple mdf sealed box such as depth height and width, i will post pictures after i get home due to the fact im in school:surprised: thankes for any of the help
