Boom! Audio High Performance 6.5 in. Tour-Pak Rear Speakers is rated 4.8 out of 5 by 4.
Rated 4 out of 5 by from Should be standard equipment These speakers make it possible to hear music clearly at highway speed. The only reason I don't give them 5 stars is that H-D should've made them standard equipment. Makes me feel like the only reason they didn't is they knew we would spend the money to buy them. The only reason I don't rate them with less stars, is they make my special needs daughter dance as she rides down the road with me.

Rated 5 out of 5 by from HUGE Improvement I agree that these should be the stock speakers. Great sounding speakers even without an amplifier. Easy plug-n-play installation.

Rated 5 out of 5 by from Nice improvement. These should be the speakers installed at the factory. Stocks were loud enough for me but popped when bass was turned up at higher speeds. These speakers dont pop with volume maxed. The grills also look better than the soft covers. At 80 mph I have volume set at 1/2 with full face helmet and 10" Windsplitter. Music is crystal clear. I have matching set in front with no amplifier.

Rated 5 out of 5 by from Major sound improvement over stock. My stock speakers distorted, popped and sounded terrible. Even had the dealership check them out, and all they recommended was to turn down the bass or replace them. I'm glad I purchased these for a replacement. Clear sound, no distortion, bigger bass and easy to hear at highway speeds. Major Improvement!

What’s the difference between 76000318 & 76000318A

Asked by: WOODY15

Can I improve the sound from the stock audio system in my 2016 Road Glide Ultra by just replacing the stock speakers?

The music gets a little distorted at high volume in my 2016 Road Glide Ultra. Can I eliminate this issue by just swapping out the stock speakers to the high performance speakers and avoid the expense of buying the additional amplifier?
Asked by: Hemi
