Sounds Good answered my call at 9am on a Monday saying the unit was in stock. The unit shipped same day and arrived 48 hours later. I installed the Amp and voilà; my Kicker CS Speakers and Pioneer DMH-WC6600NEX finally woke up. Just make sure you turn off your sub and all headunit EQ, time adjustment, etc while the Amp does its own setup. Sounds amazing. Thanks Sounds Good!.
