I was first suspicious about this subwoofer package just looking at those five reviews before me that said this sub is really nice. I hesitated a lot and decided to wait until it's in stock. I just let myself trust those buyers and ordered. When I recieved the package, the exterior box was a bit damaged that the UPS guys must have terribly carried. But the inside seemed to be alright. I let geeksquad guys install the sub. They did a really great job. Then I turned my HU on and hooked it up with my mp3 player. What can I say? It was just wow. I used to hate my car but now I love it. The musics that I used to listen are now all different. Booming is deep and soft but the bass really hits penetrating my body and shakes my hairs. If tight on budget but wanting bass, then go with this sub. You won't regret.
