I'm looking at replacing the 8 my gmc with a sa8 v2, box is a dcarcustoms box .6 cubes at 33hz. I know what the sub is rated at but how much power have people been throwing at them? Amp options are a ab vfl100.1 or a ab ph4000md, I have a ct sounds 500.1 too but would rather not use it. I'm thinking of getting a d2 and throwing the 100.1 at it and see how it likes it, vfl is 1500@1 and the 4000md is 2k@1
