GETTING A BOOM WITH HARLEY-DAVIDSON STAGE ll AUDIO

2019 Street Glide Fairing Upgrade

I have had my 2019 Harley-Davidson Street Glide for a while now, and the one thing I wanted to change was the sound of the audio.

Cruising around at city speeds the stock speaker system is not bad. But when cruising highway speeds, even all the way cranked up it, the road noise became an issue for me. I couldn't hear the music in a quality manner.

A small fix was to raise my windshield height which helped. Since I bought the bike, I had my eye on upgrading the fairing and saddlebag lids with Harley’s flagship Stage II Boom Audio speakers and amps.

A decision that needs to be made is whether you want to go Stage I or Stage II, the system cannot be mixed. Also, if you are planning on doing this yourself, beware Radio EQ MUST be updated by Harley-Davidson Dealer BEFORE operating the Audio System. Operating the audio system prior to radio EQ update will IMMEDIATELY damage the speakers. This can be done in advance although I waited until the job was complete.

The upgrade comes with detailed instruction and I suggest you read through them before installation, which is straightforward with basic tools although easier with a short-key torx wrench.

 

First thing to do is remove main fuse.

 
  

Remove the windshield by removing the three bolts at top of outer fairing.

 

Then remove outer fairing by taking out the two bolts on the inside of inner fairing on both sides.

 

Remove the harness anchor from each speaker enclosure.

Right side only: Disconnect power port. Left side only, CB-equipped models: Disconnect CB and CB antenna. DO NOT remove the module.

 
 
 
 

Remove the three screws securing the lower portion of the enclosure to the fairing support bracket

Remove the two screws securing the upper portion of the enclosure to the upper support bracket. A short wrench is required to do this.

 Do not remove any of the screws securing the speaker enclosure halves together.

Remove three screws securing the speaker enclosure to the inner fairing. Remove the speaker enclosure from the vehicle.

Remove four screws to free the speaker from the enclosure.

Disconnect wires. Remove the speaker from the enclosure.

Remove the three screws securing the speaker grille to the inner fairing. Remove the speaker.

Repeat steps to remove the remaining speaker enclosure, speaker and grille.

 
 
 
 
 
 

Install amplifier kit using the provided brackets above the radio

 
 
 

 Position the woofer over the opening in the speaker enclosure. Note the letters "A" and "B" stamped on the outer rim (C) of the speaker.

NOTE

 For the left speaker, rotate so the letter "B" is at the bottom.

For the right speaker, rotate so the letter "A" is at the bottom.

 

Attach the speaker jumper wire connectors inside the speaker enclosure to the spade terminals.

On the back of the new woofer: Different size spade contacts prevent improper assembly.

 

NOTE

The tweeter/midrange fairing speaker assemblies are side-specific.

 The right speaker trim ring has the text "BOOM! AUDIO STAGE II" to the right of the tweeter housing. The left speaker trim ring has no text.

Rotate the speaker so the tweeter is at the top, inboard of the upper mounting hole.

Fasten the speaker to the enclosure with the four screws removed earlier. Tighten.

Torque to 14–20 in-lbs

 

From the inside, insert the correct tweeter/midrange speaker assembly through the speaker opening in the inner fairing. Secure with three TORX screws removed earlier.

Torque to 9–12 in-lbs

Repeat steps for the opposite speakers.

Install one speaker enclosure to the inner fairing. Secure with 3 hex socket screws removed earlier.

Torque: to 48–60 in-lbs.

Secure the lower portion of the enclosure to the fairing support bracket with 3 hex head socket screws removed earlier.

Torque to 18–24 ft-lbs.

Secure the enclosure to the upper support bracket with 2 hex socket screws.

Torque to 48–60 in-lbs.

Repeat steps the with the remaining enclosure.

 

NOTICE

Radio EQ MUST be updated by a Harley-Davidson dealer BEFORE operating the audio system. Operating the audio system prior to radio EQ update will IMMEDIATELY damage the speakers. (00645d)

1.         See the service manual. Install main fuse.

2.         Have a Harley-Davidson dealer update the radio EQ using Digital Technician II.

3.         Turn the ignition ON, but do not start the motorcycle.

4.         Refer to the BOOM! BOX INFOTAINMENT SYSTEM section of the owner's manual. Turn the radio ON. Make sure that all speakers are working and front/rear fader function is operating correctly. If not, check speaker wiring. Understand that buzzing, squeaks and rattles could be heard until outer fairing is installed.

5.         See the service manual. Install the outer fairing and windshield.

6.         Avoid direct contact with speaker grilles by a pressure washer. Damage to speakers can result.

I loaded the bike up and took it to Space Coast Harley Davidson, my local dealer. The tech was super knowledgeable with all my questions as usual and had the bike upgraded in about 30 minutes.

 
 
 
 
 

 I have been able to play with the system for a little time now and have to say I am impressed. When thinking about starting this project, I read some bad reviews and good ones. I also had asked around at my local dealerships too.

The majority of the reviews are all very positive on the system. When it comes to electronics, nothing is perfect, and if it fails it will usually do it within a month. The bike has been wet, been almost frozen, baked in the sun and played hard every time I am out. The system could have a little more bass, but the audio contains outstanding clarity.
 
Everybody, who heard it is amazed. This blows stock away and leaves me no choice but to install saddlebag speakers, as I definitely want more. Highway speed sound is great but at race track speeds a little bump in volume won’t hurt.
