this item is amazing for the $100 price point it is super massive for a 8 inch sub I took it out of the box and I'm like holy crap and it's got enough strength I just have one I put it in heavy duty base tube the downfall is as I got to figure out how I can do my amp cuz it keeps kicking off because the sub is too powerful itself LOL but I'm working on it recommend definitely buy
