This is one of the best subwoofers ive ever heard. I have one hooked up in my car with a 1000/1v2 and it bangs hard! ive never heard anything like it. The only down side is they are a little spendy and are really heavy. But are definatly worth the money. If you can get your hands on one of these, they sound great and bump hard. Plus it will make everyone in your neighborhood jealous.
