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!
They sound great for the money!!
