Rainbow Audio

Has anyone used this brand?
How does it compare to the stock sound system of BMW?

I haven't used them personally but I remember coming across them many times when I was building out my Subaru audio system. Many of the high end builds I found in my research used Rainbow. They can get pricey though, and they are hard to find since the company forbids online sales.

High-end car audio, but I have never used them.
