IT IS ! ! ! ! ! ! ! It sounds so good I can barely turn the volume up because it's so loud. Whether you use radio or iTunes its completely awesome. J&M even sends a USB stick with every conceivable type of music sample on it so you can get a true perspective of the dynamic range of this amp and speaker setup. Now I can understand why Spazz turned his on in the driveway and walked a half block away recording the sound at far distances. I am 110% floored by the difference in this and stock Boom series.
What I liked about John's kit is everything you can possible need is in it. For any of you "on the fence" and want a great system at a modest price, this kit
(part # RXEX-250SP2-14SG) with John's SGF discount was $799 and was fun to install ! 5 Stars here
