I have a 02 Escalade. It comes with a bose system. I want to add some subwoofers in it but I don't know anything about subwoofer. I interested in Solo X 18" or JL w7 series. I need help on making a decision. I want a subwoofer that plays good with ALL types of music. I don't want a subwoofer that can only plays rap good but sucks at country. I want both!!! What is a SP or SPL or something like that? If I add the subwoofer do I need to change out all of my speakers or my bose speakers are good enough. I don't listen to really loud music (harmful to my ear
but I would like to crank it up every now and then. I looking for accurate, precise, and a good system. Thanks for all the help!!!
