INSTALLATION
Front Fairing Speakers, Electra Glide Models
NOTE
To prevent permanent damage to the woofers and outer fairings, the original speaker adapters MUST be reused after the following modifications are made.
1.
Peel off and discard the plastic grille and fabric from the OE adapter faces. Clean off any dirt or dried adhesive.
NOTE
The speaker grilles are side-specific. The grilles install so that the tweeter is to the outboard side of the vehicle.
2.
See Figure 1. Position the correct new speaker grille (2) against the face of the adapter (1) as shown, with the thick edge of the adapter up, and the tweeter (3) to the outboard side of the vehicle. Feed the tweeter wires out between the grille and adapter on the outboard side. Position a new speaker (4) against the rear face of the adapter as shown, with the spade terminals (5) pointed up.
3.
See Figure 2. Connect the wires from the grille-mounted tweeter to the spade terminals (1) and (2) on the back of the speaker. Different size spade contacts prevent improper assembly.
4.
Align the mounting holes in the speaker, adapter and grille. Use the two longer TORX® screws removed earlier to fasten all three components to the inner fairing through the two top holes. See Figure 1. Use a new Phillips head screw (6) from the kit in the lower outboard hole, capturing the fairing support brace under the screw head. The lower inboard hole is not used.
5.
Tighten the lower screw to 2.5–3.2 N·m (22–28 in-lbs). Tighten the upper screws to 4–5.7 N·m (35–50 in-lbs).
6.
See Figure 2. Install the socket terminals from the vehicle harness to the spade terminals (3) and (4) on the back of the speaker. Different size spade contacts prevent improper assembly.
7.
Repeat Steps 1 through 6 for the remaining speaker on the opposite side of the vehicle, then proceed to Rear Speakers, All Models or RETURN TO SERVICE as appropriate.

See Figure 3. Remove the liner from the adhesive backing of the gasket strip (4). Carefully position the gasket to the front of the new speaker grille (2) outer flange, and press firmly into place while working around the entire flange perimeter. Cut off any excess gasket material, leaving no gap.
3.
Position a new speaker (5) against the rear face of the adapter (1) as shown, with the spade terminals pointed inboard and down. Align the mounting holes in the speaker and adapter. Use the Phillips-head screws (6) removed earlier to fasten the speaker to the adapter. Tighten the screws to 0.7–1.4 N·m (6–12 in-lbs).
4.
Position the speaker grille against the face of the adapter as shown, with the tweeter (3) to the outboard side of the vehicle. Feed the tweeter wires downward and out between the grille and adapter.
5.
See Figure 2. Connect the wires from the grille-mounted tweeter to the spade terminals (1) and (2) on the back of the speaker. Different size spade contacts prevent improper assembly.
6.
Align the mounting holes in the speaker adapter and grille. Use the TORX® screws removed earlier to fasten the adapter and grille to the inner fairing. The top outboard hole is not used.
7.
Tighten the screws to 0.7–1.4 N·m (6–12 in-lbs).
8.
Install the socket terminals from the vehicle harness to the spade terminals (3) and (4) on the back of the speaker. Different size spade contacts prevent improper assembly.

RETURN TO SERVICE
NOTE
Before installing the outer fairing, check that speakers are operating correctly, understanding that full sound quality and fidelity will not be achieved until the outer fairing is completely installed.
Verify that the ignition key switch is in the OFF position before installing the main fuse.
  1. Refer to the service manual and follow the instructions given to install the main fuse.
  2. Turn the ignition key switch to IGNITION, but do not start the motorcycle.
  3. Refer to the ADVANCED AUDIO SYSTEM section of the owner's manual and turn the radio or CD player ON. Make sure all speakers are working and front/rear fader function is operating correctly. If not, check speaker wiring.
  4. Install the outer fairing and windshield per service manual instructions.
IN USE
During use, the domed tweeters may appear to take on an orange tint near the base of the dome. This tint is a natural property of the Ferrofluid used to provide proper voice coil functionality. This does not affect speaker performance.
