Im looking at upgrading the speakers on my 8, the bose system is not sounding so great after all these years. Im looking at something that midrange price and quality. Any brands yall suggest to get?

04 RX8 GT
Bose sound system
Stock head unit.

I'm running all diamond in my car the highs are crisp, mids are nice with alittle base on the componets. And I do run subs to get the bass. They are on the high end in price compared to some but I am very happy with my choice. I would go rainbow, mb quartz over what I have but at a higher price
