Did you have it in the M3? Can you power the Enhanced system with just this amp?
You have any pics of where it was installed?
Sorry. I have done no reading on stereos, but love these amps.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
