I just got my Cruze this week and love it. One of the only cons I have seen so far is the upgraded Pioneer 9 speaker system. Honestly, I cant complain too much. I got the Allstar package with my car which includes sunroof and upgraded Pioneer speakers. The promotional price on the package is the same price as the sunroof alone so it is basically a free upgrade to the Pioneer system. I don't know if I am just used to the Bose speakers in my 2000 Cadillac, but the sound just is not up to par to me. Has anyone with the Pioneer sound system done any tweaks they can recommend to improve it?
