Boom! Audio Stage I/II Fairing Lower Speaker Kit is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Sounds Amazing sound no distortion. It is not cheap amp and other parts for install and install cost adds up to at least $1,600 but you do get a bang for your buck.

Rated 5 out of 5 by from These are awesome If you love good clean highs in your music, this is the best way to go, of course you will need the amp and harness, that run up a unrealistic cost! But sounds awesome

Rated 5 out of 5 by from One of H-D's best upgrades Great fit and finish. They look like original equipment and sound terrific, having a full spectrum range that fills the air with sound easily even at fwy speeds.

Rated 5 out of 5 by from Awesome Upgrade These made the already "Bad Ass" sound system on my 2016 FLHXSE CVO Street Glide even Badder! Powerful bass, crisp and clear sound at any volume. I'm totally gonna go deaf from abusing my tympanic membranes! :) Be prepared though, these speakers are just the beginning of what you need to properly install on a Boom Stage II system. Plan on spending $1800-$2000 for all the parts and labor by the time it's all said and done.

What about the Tri-Glide?

Fitment shows the other Twin-Cooled models but not the Tri-Glide.
Asked by: legs290

Will these work on my 2014 FLHTKSE w/Boom 2 upgrade already?

I have already upgraded to the BOOM2 system- fairing, saddle bag and tour pak. Would love to install these on the lower fairings! Thank you
Asked by: Chief14

Is thee a way to purchase just the speaker pods for my 2017 FLTRU

I'm running J&M speakers on my 17 RGU, and I'd like to ad lower speakers to it. I bought my speaker kit through my dealership and now they say the only way to get the speaker pods is to also buy the HD speakers. I won't be using the speakers there not compatible with the amp from J&M audio. I would really like to ad more speakers and hope that your customer satisfaction will allow the release of this item so we can continue to make our Harley Davidson's Our's Thansk
Asked by: Switchbacksteve

What other items do I need to order for a complete install of these speakers on my 2017 FLHXSE? Thanks.

Asked by: Iancvo

Will these work with the existing amp on my 2015 FLHXSE?

Would the only parts I need be the speakers and the installation kit (76000734) or is there more needed?
Asked by: JoshL
Hi JoshL, Yes, the Boom! Audio Stage I/II Fairing Lower Speaker Kit will fit with your 2015 FLHXSE. FYI, this system will not fit with models equipped with Tour Paks. You will also need Installation Kit P/N 76000734. If you have additional questions, please contact your local dealership. Thanks!
