The whole idea of this post actually came to me after i switched from a pair of 13w7's to 2 pioneer 2000spl's. i noticed the sound with the pioneer's was sticking in the car but the jl's well lets just say with the windows down they were insane. They give you that thump in your chest even when you stand oustide the car. I took out the jl's due to the cold weather. since my whole trunk is being takin up with the jl's fiberglass box i cant place the pioneers there so im stuck with them sitting on the back seat but do you think the issues im having with the pioneer's is a result of their placement, perhaps the box or do they just play loud in the car and not outside?
