I just picked up a ‘20 Rebel w/the Harman Kardon (19 speakers/900 watts), and it sounds amazing. Definitely one of my favorite features with the truck. I had concerns from reading some of the reviews, particularly that it was it underpowered. That’s certainly not the case with my system. It has detailed highs, clear mids, and deep lows. The bass thumps, but can be easily controlled by the EQ as desired. It sounds 10X better than the upgraded Bose in my C7/Z06, and on par with the HK in my Jeep GC. If you’re on the fence, jump!
