I'm getting a new Mustang. I just want to know if the 1000 is worth it over the Shaker 500. I DO NOT want to tear everything out and go aftermarket unless I have to. I want to know if the Shaker 1000 is enough to feel in the drivers seat. In other words, if I turn the bass up, will the subs literally shake me? Like in a way that I can feel my hair moving? Know what I mean? haha
