If you want hard hitting bass but don t have the space then this bass tube sub is the answer. It is easy to install and can go virtually anywhere such as: behind truck seats, in hatchbacks, and in most cars, vans, SUVs and RVs. It is equipped with an 8 inch blue Polypropylene woofer, a 2 aluminum voice coil, and a stamped steel basket for precise voice coil alignment. The specially treated black rubber edge suspension and ultra strong Polypropylene dust cap provide strength, reliability, and soft light suspension for the woofer thus increasing efficiency. It handles 400 watts, yet only requires minimal power to drive it efficiently. What makes this work so efficiently is its acoustically tuned bass reflex port design which delivers twice as much bass response.
