I agree, the prices on their speaker package to seem inflated. However, they are plug and play and require no splicing and soldering of wires. This is nice. I know the price is a little high but what im curious about is the sound quality of the upgrade. They are using Rainbow speakers and I have never heard these speakers in person. When you did the MB Quartz upgrade on your 7 did you do the installation? Did you cut and solder the wires?
