This must be a hidden gem among folks who want a boom in their system. Why spend 400 dollars on a sub when you can have this sub at 65 bucks. NO one is going know the difference when your on the road with these hitting vs the so called "higher name brands" like most folks have said they know people who spend 4k on subwoofers alone and then you put the same subs such as these in another friends car and they hit just as loud if not louder NO ONE knows the difference. I need to buy more of these....
