I have a Boss sub and it's been very good for me for nearly three years now. That particular Chaos sub is way more efficient than the kicker subs and will do better in the smaller internal volume. Plus, you get two of them for basically about $80. Even if they only last a year, that's still a good deal. You can always replace or upgrade the subs later as you'll already have the enclosure. I'd jump on it.
