I’m about to place my Rubi order and trying to figure out which top to get. The stock hard top creates a resonance that’s unpleasant to my old ears. A friend has a JLUR with the Mopar insulation which helped some, but didn’t totally eliminate the sensation. I was wondering if there’s anyone in the Denver area with a 4 door, Sound Assassin and Hot Heads that wouldn’t mind giving me a 5-10 minute ride. I’d prefer the hard top, but if I can’t eliminate the resonance, I’ll go for the Power Top.
