UPDATE:
I purchased the Pioneer Mic for Auto EQ from Amazon and it was delivered today. The system took about 10 minutes to run through it's samples.
It's hard to believe the difference it made in sound quality. So much better. The best 20 bucks I spent in a long time. If you own the HU, you must buy the mic and Auto EQ. Once done, you can still select from Natural, Vocal, etc. Flat sounds the best.
No new apms or speakers but the sound system, with the addition of this head unit, is amazing. I've heard from local dealers that Pioneers are not as good as Alpine and Kenwood son
