One thing I really dislike about Clarions (I have a lower model in the CZ series, not overly impressed with it) is their wiring out the back. Instead of using a more modular design by having jacks rather than plugs, they have a huge mess of wires sticking out the back, which just gets messy once you wire up the speakers, sub, etc. It was problematic in my w126, IIRC since there wasn't much room to fit the huge mess of wires. I usually stick with Pioneer, I've found their products superior in sound quality (I am an audiophile) and interface.
