I know that there is a ton of info regarding upgrading the sound system...that's why I am so confused! I did search the aechives as well as MZ3 Net. So my question is this: What speakers do I need to replace and/or what sub woofer do I need without distroying the look of the car & still have some trunk space. Also, I need to find someone to do this, where to start???? I have a 2000 2.3 Thanks Connie
