Pioneer CD-MC20 Microphone
Crutchfield Customer Review (What's this?)
After plugging the mic in and running the auto EQ I had some pretty decent balance between four speakers and the sub. I had to adjust the passenger side front speaker up a little. The EQ settings were horrible. I manually reset the EQ based on my listening/hearing style. The crossover was set to turn off the high pass filter on my front speakers. That caused some major clipping problems so I turned the HPF back on. The bass was set to cut off at 100...I changed that to 80. All in all, it was close but I had to tweak what it did. It is now just about where I had it set before using the auto EQ feature. Honestly...these setting can be done by ear much better. But if you're not good at setting these things manually this will get you close.
Pros: Easy for novice to get better sound out of their system.
Cons: Not close enough for audiophile.
