Gotta love that MC4000M... it's by far the best amp I've ever heard, and/or had.

I have one small gripe though. It's got 6 channels, and built in high-pass and low-pass crossovers, but when you want to run it it in 6 channel mode using the high and low pass xovers, it takes the low pass signal from the mix of channels 1-4. That would be great if you had a 4 channel out deck, but most of the high end ones these days also have a non-fading sub out. You can't use this with the low pass xover for channels 5 and 6. YOu either have to use an external xover(potential for added noise) or rewire the amp(what I chose to do). Another thing is that the amp is so huge, you have to mount it on the sub box. I was thinking of mouting min on the back of the back seat but it was to big!! When the amp sits on a bux with a couple 12" It tends to vibrate a little. You'll have to dampen inside the amp, and between the amp and box to prevent vibrations at mid bass frequencies (50hz-90hz). Good luck with yours. I know you'll love it!
