I just traded in my 2003 Mazda6i today for a 2006 Mazda6s. I love it, however my speakers in my 03 are much better sound. The 03 had premium sound but no bose. I turned my 03 up to 12+ and the mirrors and car shake and from the outside it sounds really good a clear & goes boom. The 2006 however is premium sound with out bose also but for some reason it does not sound as good. I have to turn it up to 20 to get it to do the same thing but even then it does not tottaly sound the same. In my 03 it was like tottal surrond sound a I LOVED IT!! Any speaker suggestions as I do not know a whole lot and for a descent price that would up grade my sound. Anyone else notice the diffrence between the 03 speakers and the 06's. Maybe they cut some corners. Any advice would be helpful and maybe some audio clips if anyone has some although not sure how it would sound. Anyone know what original speakers was in the 03 to the 06.
