Hi. I don't know too much about car audio, but I do appreciate good SQ. I have a nice setup in my 97 Seville that consist of a 13w7, 1000/1, 300/4, and some MB Quarts speakers. It sounds alright but needs tuning in a huge way. Anyway, I am here to start looking into a system for my Cadillac SRX. Hopefully I will learn a thing or two.
