For anyone buying subwoofers I would advise you to check out DC sound lab. Their subwoofers are top notch in SQ and get for the most part louder than any other sub it it's price range. There are also so many options that they offer, not only their level 2-5 but they also have neos and level 6 that is not advertised but you can get from special order. You can upgrade nearly every part of your subwoofer from a reinforced surround to a carbon fiber dust cap with your choice of color (that looks sëxy as hëll!) also you can upgrade your voice coil on any of the levels advertised. They deal with you like you are an actual person not just a customer. Everyone they deal with they can get to know on a personal level such as you can call up the OWNER of the company that works with customers on a regular basis to come up with new ideas so if you want something special on your sub you can just ask them and they will do their best to make it happen. It just seems like an obvious choice to check them out considering their prices of a comparable subwoofer of there's is half the price of a kicker sub while sounding just as good if not better.
