Anyone using these? They can be had for $150 from $300. They have good reviews but looking for anyone with personal experience.

I have them in my Passat. They sound good for a what they cost with 100w RMS going to them. I liked how the tweeters of my infinity reference components sounded better but the Kenwoods do have far better midbass response. The tweeters aren't the smoothest but will sound 100 times better than the stock speakers.

I plan on going the same route. I installed a set of MM6501's in a C5 and it sounds great!
