Okay Ed, look I have a 2001 Toyota Camry, I have a Memphis PR-1000D amplifier and I am going with Kicker CVR's, I need to know 8, 10, 12, 15 or 18? I am not competing, just trying to make the trunk rattle but be able to have some clarity. Choose one size? I don't care about SQ or SPL, I am an average "Joe" who has some money to spend at the local Best Buy and I'm am going with whatever box they have them in on the display shelf, now for heaven's sake just pick a size, Please?
