Well I need some advise on which one of these 8's is better for everyday use? I already have a .6 ported box and ill be getting the dvc 4ohm and a 600 watt at 2ohm amp. I listen to mostly rock and country. I've looked at the spec on both subs and the sa-8 will take 200 more watts. But I was wandering if the e8 would be loud enough?? Since its a little cheaper the e8 is what im thinking but since Im only gonna have a 1 sub setup I want it to be right.  I already have a rockfosgate p2d48 and its alright but I was going for quality with my little setup not volume. A little help please
