I upgraded these from my old planet audio TQ12 and i'm so satisfied! Have these in a ported ground shaker box and Boss Phantom series 1500 watt amp and let me tell you these things pound. I only have them up 1/4 up so far and are way louder already than my old system was turned all the way up. Boss all the way you will not regret it! Thanks onlinecarstereo!
