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

  I upgraded the fairing to Stage II recently and just want more. You you can see that article at:

 https://www.bikernet.com/pages/GETTING_A_BOOM_WITH_HARLEY_DAVIDSON_STAGE_ll_AUDIO.aspx 

 Needed? Questionable, but definitely wanted more Boom! 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 a 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. This involves some finesse with cutting tools as both saddlebags need to be modified.

 The speakers in this kit are for use ONLY on specific 2014 and later Harley-Davidson audio systems. See the P&A retail catalog or the Parts and Accessories section of www.harley-davidson.com (English only).

Note: Using these speakers on 2005 or earlier Harley-Davidson audio systems WILL cause permanent damage to those systems.

 
 
 
Installation: 

 First thing to do is remove main fuse.

 Remove seat.

Remove the ECM caddy from the top of the battery.

Disconnect both battery cables, negative battery cable first.

Remove battery.

Remove right side cover.

Remove left side cover.

 

 

Drain and remove gas tank.

 

 

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

 

 

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

 Remove the two bolts securing the electrical caddy under the left side cover.

 

RIGHT SADDLEBAG DRILLING AND CONNECTOR INSTALLATION

Remove all items from the right saddlebag and remove saddlebag.

 

 Remove bolt that retains the handle in the lid.

 Then remove 2 screws in the cloth stop and remove 3 bolts and nut for cable to disconnect lid from lower bag.

Remove the 4 torx bolts in the lid to separate frame from upper lid.

To minimize damage to paint during cutting and drilling. Cover both sides of the area being drilled or cut with masking tape.

Place the saddlebag on a protected surface with mounting (inboard) side facing up.       

Place the template on the saddlebag. Align the grommet and latch fastener openings. Drill the hole at locations and , beneath the remark "S'BAG SPEAKER ONLY". 

 

 Drill four holes .177 diameter holes for the lower connector flange mounting locations.

 Drill a hole .886 diameter hole for the connector location.

 Verify pilot hole placement with the four-way flanged connector [C36A] (3) on the harness.       

Test-fit the connector. Shape the hole as seen on the template if necessary.   

Four-Way Harness Connector Installation

Remove the metal plate from the four-way bulkhead connector on the saddlebag harness. Insert the connector through the saddlebag hole from the inside.   

Slide the metal plate back onto the connector outside the saddlebag. Secure the connector with four socket head screws from inside the saddlebag. Tighten and torque to 35–40 in-lbs.

 Now for the Left Saddle Bag, remove any items and remove the saddle bag.

Remove left side lid using same procedure as with the right

 Carefully cut the cutout (4) in the template for connector [288A] on the dashed line.

  Drill two pilot holes (5) for the connector flange mounting locations.

 Remove template. Verify size of cutout (4) with the 18-way flanged connector [288A] on the saddlebag harness (see Figure 12 , Item 4) from the kit.        

Cut the cutout for connector [288A] into the saddlebag wall.  

Drill two holes at the connector flange mounting pilot hole locations.

Length/Dimension/Distance: 7.25 mm (½ in)

 

Insert the pin side 18-way bulkhead connector (3) from the saddlebag harness through the connector cutout (6) from the inside. Secure the connector from outside the saddlebag with two socket head screws (4) and washers (5). Tighten.

Torque: 4–4.5 N·m (35–40 in-lbs) M5 hex socket head screw.

 

 Snap the harness cover over the 18-way connector. Secure with a cable strap. The harness routes inside the saddlebag after the amplifier is mounted.

Amplifier Bracket Installation

Clean the inside rear and bottom surfaces of the saddlebag with a 50-50 mixture of isopropyl alcohol and distilled water.

Verify that all four tape strips are contacting the saddlebag.

Remove the four pieces of protective backing from the amplifier bracket tape strips. Position the bracket as shown.  

  

 Install the amplifier pin studs in the amplifier. Tighten.

Torque: 9.4–12.2 N·m (7–9 ft-lbs)

 

 Install the grommets  

Amplifier Installation

Position the amplifier with the grommets in the holes in the bottom of the amplifier bracket. Slide the top into the bracket. Install the hex socket button head screws. Tighten and torque to 7–9 ft-lbs.

 

Plug in connector of the saddlebag harness to the top of the amplifier. Route the saddlebag side harness inside the left saddlebag. Clean the inside bottom and side surfaces of the saddlebag along the harness path with a 50-50 mixture of isopropyl alcohol and distilled water. Secure with cable straps and bases as shown. 

 

 Route the vehicle-side amplifier harness in the saddlebag mounting area, beginning the vehicle. Route the harness around the rear wheel sprocket, following the saddlebag support rail.

Route the harness behind and underneath the frame, into the under seat battery area.

Use cable straps to tie the harness loosely to the saddlebag support. Use the large hole near the saddlebag rear attachment point or one of the cable strap slots along the bottom of the support.

Temporarily install the left saddlebag into the support assembly. When sufficient clearance is confirmed, tighten the cable straps. Remove the saddlebag.

Confirm that the vehicle-side harness connectors reach the saddlebag connectors.

Confirm that the amplifier harness connectors and harness routing are clear of all moving parts.

Confirm that no contact is made at full extension and compression of the shock absorber.

Continue routing the harness forward on the vehicle.

 

 Locate the black, four-way Molex connector [296A] near the back of the under-seat area. FLHX/FLTRX models: On a jumper harness coming from the fairing. FLHTCU/FLHTK models: On an adapter harness with two 16-way ([162C] and [162D]) and two four-way ([296A] and (297B]) connectors. With ONLY ONE Stage II amplifier installed in the rear: Remove the plug in the [296A] connector. Connect the amplifier harness. With TWO or more Stage II amplifiers installed in the rear: Plug the audio input harness (15) from this kit into connector halves [296A] and (297B] on the adapter harness. Plug amplifier harness connector [296A] into the audio input harness.

Locate the 2-way Delphi CAN connector [319B] (1) under the right side cover.

The cap is a terminating resistor pack secured to the electrical caddy. Remove connector [319B] from the resistor pack.

Connect [319A] (See Figure 18 item 9) from the harness to [319B] of the vehicle.

If this is the only (rear) amplifier connection in this installation, connect the [319B] side of the harness back into the terminating resistor pack from step "B" above. If multiple rear amplifiers are used, daisy chain [319B] from this harness to [319A] of the next amplifier harness. Always verify that the remaining connector [319B] is connected to the terminating resistor of the vehicle.

Locate connector 299 on the vehicle under the inner faring. This connector may already be connected to a faring amplifier.

 

 

 Install 69200921 "Y" to vehicle side 299, with one end to the faring amplifier harness.

Install the 69201545 jumper (If a 69201545 jumper has already been installed on vehicle skip ahead to "e". Do not install more than one 69201545 jumper.)

Route the 69201545 jumper though the inner faring and into the wire trough following the Faring harness routing.

Locate the end of the 69201545 jumper under the RH side cover near the [319] connectors. If a 69201545 is present from a prior install use a 6920921 "Y" under the RH side cover to connect [299].

Route the battery terminal branch to the battery terminals, but DO NOT connect the battery cables now.

 

Route the longer harness branch (with six-way socket connector [36B]) to the right side of the vehicle. Use cable straps to tie the harness loosely to the saddlebag support. Use the large hole near the saddlebag rear attachment point or one of the cable strap slots along the bottom of the support.

 Temporarily install the right saddlebag into the support assembly. When sufficient clearance is confirmed, tighten the cable straps. Remove the saddlebag.

Confirm that the vehicle-side harness connector [36B] reaches saddlebag connector [36A], installed earlier.

Confirm that the amplifier harness connector and harness routing are clear of all moving parts.

Confirm that no contact is made at full extension and compression of the shock absorber.

 Installing speakers in the lids.

 

 

 Position the smaller tweeter speaker is toward the rear of the saddlebag as shown.

 Secure the speaker with the four long screws. Alternately tighten screws. Tighten and torque to 12–15 in-lbs.

Place rubber washers into the grille mount well.

Place the speaker grille into position over the speaker face.

Secure with the four short screws (3). Alternately tighten the screws. Tighten and torque to 12–15 in-lbs.

Repeat steps for the opposite-side saddlebag cover.

 Install the grommet from the original cover in the lever hole.

 

 Install the lever bolt into the latch assembly.

 Position the latch assembly and verify the hex head bolt stayed in position. Lift the latch assembly and position the speaker end under the locating tab.

 To install the latch assembly, pull the latch assembly towards the center of the cover to clear the cover locating tabs.

 Install three of the original four latch assembly screws. Tighten and torque to 19–29 in-lbs.

 Hold faceplate in place and install three screws. Tighten and torque to 45–55 in-lbs.

 

 Please note: Ambient temperature should be at least 61 °F for proper adhesion of the gasket to the saddlebag cover.

 This step is essential to prevent water intrusion.

 Clean the area with a mixture of 50-70 percent isopropyl alcohol and 30-50 percent distilled water. Remove the protective seal from foam gasket and install the foam gasket in orientation shown by applying pressure to the adhesive tape.

 Install the handle. Tighten and torque to 45–55 in-lbs.

Repeat for the other saddle bag lid.

 

Connect both two-way audio connectors from the amplifier harness to the mid-range/tweeter connection and the woofer connection on the underside of the speaker. The connectors are unique and only fit one way.

Add cable straps and wire retainers from the Amplifier Installation Kit to retain the harness inside the saddlebag as needed.

 To prevent possible damage to the sound system, verify that the ignition switch is OFF before attaching the battery cables.

 Connect the battery terminal branch to the battery terminals (red positive cable first).

 Apply a light coat of petroleum jelly or corrosion retardant material to battery terminals.  

 Install the ECM caddy per the service manual. 

 Install gas tank.

If upgrade to radio is already done install seat and fairing and windshield. In my case I did not, so off the dealer to get upgrade to radio. DO NOT POWER ON RADIO or immediate damage will occur to speakers.

 Install main fuse.     

 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 am impressed with Harley’s flagship speaker and amp system. The bike has been wet, been almost frozen, baked in the sun and played hard every time I am out which is quite a bit. The system could have a little more bass, but the audio is outstanding in clarity.

 
Everybody who listens is amazed. From stock with an average of 96 decibels cranked all the way up to 2 amps and 4 speakers pumping 600watts I recorded an average of 109.1 decibels. This does not sound like much but with added clarity and volume increase, I’m blown away with this setup. I’m pretty sure it is not needed, but I am considering adding lower fairings and speakers just because. An added note when cleaning your motorcycle do not blow pressure washer directly on speakers as this may damage them.
