Have the Velcro strips used to my subwoofer in the trunk of my car to fix the carpeting. The two "hook strips" I have it just stuck together to join both and the "Velcro strip" completely omitted. (The subwoofer has a felt cover.) Thus, everything holds bombproof. In tight corners it moves no part and during emergency braking, he also stops (may be because he is resting just behind the back seat.) Anyway, they keep what is promised and are really "Extra Strength".
