edit: jus read the reviews on crutchfield about the alpine and sonds hot, I have aftermarket speakers fronts pioneer and 6x9 infinity and I'm sure they are going to sound better, thing is alpine is 45x4 and i blieve sony is 52x4 will that make a difference...oh and I found alpine brand new in box for 150 shipped on ebay so I might do that
