13x20x22??? What is what rofl...Width, height, depth?? What is 25" or 26" long? If my calculations are somewhat close it's 1.9ft^3 tuned to 39hz which is a bit high.
Make a custom box to fit the sub..The enclosure definitely matters.
Save up some money and get a real sub like the Sundown Audio Z v. 2 10" it will laugh @ 1k rms but sound good. Never any reason to impulsively buy cheap garbage and regret the purchase when if you'de just saved for another month you'de have something actually worth a ****.
