I must say I am happy surprised with this subwoofer. I searched for a long time for the right subwoofer for my truck and space was limited. I wanted SPL along with clean quality bass. Most of the time square subs along with Kicker get slammed for the sound quality. After I had purchased the subwoofer I read many reviews of the 15, 12 and 10 inch sub of this model and most people said it is loud and simply sloppy. I want to remind people this is an 8 inch sub. It is meant for a small box in which case that gives you the tight accurate bass many people are looking for. If you build a solid box and give this some nice power it will sound amazing. It is loud and clear you just need to take your time tuning it because it will start to sound different when you turn it all the way up.
