Yea I've looked at the sa-8 as well. I listen to rock and country which one would I be pleased with??? I like the e8 because its cheaper and I believe it'll be plenty of sub for me. I currently have rockford fos p2d48 so the e8 will be a lot better and I know the sa-8 would be massive difference. Anyway help me decide. Based on your knowledge, oh I've never heard either one!!
