I wouldn't spend the money on those. Get some Image Dynamics IDQ10s a small sealed box and a decent amp. Also check out www.carreview.com for reviews on subs. You'll notice there aren't any reviews at all for those subs, and any of that company's subs at all for that matter. The IDQ subs are about 150 bucks on ebay. You can pick up a decent kenwood amp pretty cheap.
