   GIBMUSIC From Texas Made

Look at my ratings, can I say more? I love this thing I have a single one running at 2ohms in a .5 cubic foot box with 400watts, and it bangs with the big boys. Sounds just as good as many higher priced and larger subs. This sub has good quality bass you will be surprised.
