ok so i have heard tons about how stupid loud these things are and that is sweet, i love it. I was looking to put a 15" BTL in my ext cab s10 pickup and i was just wondering how loud this would be. I need a perception of DB's here, i see some vids where their windows are flexin, i know im not gonna get anywhere near what that 02' caddy has but i want my windows to flex some, how many db's does that take and do you think it can be done with one properly ported and tuned 15" BTL?
