Hey everybody, I'm new here and new to Fi products. I heard a single 15" in a local parking lot and was blown away. I'm looking to purchase an 18" BTL (any other suggestions?) enclosed in a ported box. I'm trying to stay under the $1500 mark . I really have no idea what amp I should purchase or if 2 15" will be louder. I'm 16 and I don't have my car yet, but I will be getting a 2004 Pathfinder. P.s I'm trying to out do my friends 2 15" mojos with a 3000 watt stetsom amp. Any suggestions on a set up would be awesome (and the final cost of course) Thanks, Daniel
