Review: Good quality, well worth the money. Helped me enhance my PRV speakers even more. And being that I'm not a professional so I don't even think I have the adjustments correct to get the full potential of the speakers and they still sound great. So many wonderful features to play with. One of my favorites is being able to turn amps on in sequence. Functions very well, very easy to install, and like I said, I'm a non professional.
Review: This makes a huge difference in clarity with all my speakers in my truck. The delay setup for driver listening is amazing, I’ve never heard music like that ever in my life! And I swear I am not getting anything out of this review as it sounds to good to be true… well I believe so!
