Hello friends I am new but not to the systems. I came here to talk audio that ive Fallon in love with over the past couple months. I have a jl audio 12 inch and a pyramid amp which says 600 watts! I like it my friend says jl's bottom subwoofer can be 150db and mines a couple higher mine is the w3 maybe I'm hoping I'm around 160 db! He says it the loudest sub he ever heard (and he runs kicker so he knows what he's talking about). Anyway hope to ask questions and talk about car speakers!
