Mounting
- See the section “Installation Precautions” on page 2.
- Keep connection cables away from any pinch points, moving parts, or any hot exhausts.
- Do not install the speakers where they may obstruct the rider’s view or inhibit any safety features on the vehicle (e.g. lights, horns, brake levers, etc.).
- Before you drill any holes, investigate your vehicle’s layout very carefully. Take special care when you work near the fuel tank, fuel lines, hydraulic lines, and electrical wiring.
- To ensure the security of the mounted speakers, always check the mounting conditions (e.g. clamp fastening) of the speakers before each vehicle ride.
Mounting the speaker pods
- Find a safe and ideal mounting location on the handlebar. Make sure the speakers will not obstruct the rider’s view or any safety features.
- The supplied clamp is pre-attached to the bottom of the speaker. Unfasten the clamp through the mounting nuts.
- Fit the clamp around the handlebar of your vehicle. Remember to attach the supplied rubber shims over the mounting bar to secure clamping and prevent abrasion.
- Re-fasten the mounting nuts to tighten the clamp. Before fully tightening, adjust the speaker so it points directly at the rider.
- a. Mounting nut
- b. Rubber shim
- c. Speaker clamp
- d. Mounting bar (0.75” – 1.25” in diameter)
Mounting the amplifier
You can secure the power amplifier in your vehicle using the supplied screws.
- Find a suitable location in the vehicle to mount the amplifier. Make sure there is sufficient air circulation around the intended mounting location.
- Secure the amplifier as follows:
- Use the four screw holes on the amplifier to mark the mounting holes on the mounting surface.
- Drill the mounting holes in the mounting surface.
- Place the amplifier in position, and attach the amplifier to the mounting surface using four supplied screws, spring washers and plain washers.
Mounting the power/volume knob
Mount the power/volume knob in a safe, easy-to-access location where it will not impede the rider’s ability to drive safely. Secure the power/volume knob using the supplied zip tie.
Wiring
- See the section “Installation Precautions”.
- For safety, disconnect the negative terminal of the vehicle battery prior to wiring.
- Keep connection cables away from any pinch points, moving parts, or any hot exhausts. Secure the connected cables.
- Reconnect the negative terminal of the vehicle only when all wire connections are correctly and securely made.
Power Source Connection
Option 1: Direct connection to the vehicle battery
Note:
Direct connection to vehicle battery consumes power. Always use the inline
power/volume knob to cut the battery power when the speakers are not used.
- Using the supplied power cable harness, connect the black cable (labeled “GROUND” ) to the vehicle’s metal frame or to the negative battery terminal and the red cable (labeled “+12V”) to the positive battery terminal.
- Connect the power cable harness to the connector of the power cable (labeled “POWER”) which is attached to the amplifier.
Option 2: Connection to ignition switch
When connecting the speakers to the vehicle’s ignition switch, the speakers
can be automatically powered on or off with the operation of the ignition
switch.
- Locate and identify two power wires in the ignition switch, one for switched +12V and the other for negative/ground.
- Using the supplied power cable harness, connect the black cable (labeled “GROUND”) to the negative/ground wire of the accessory power and the red cable (labeled “+12V”) to the switched + 12V wire of the accessory power. Insulate the cable connection with electrical tape.
- Connect the power cable harness to the connector of the power cable (labeled “POWER”) which is attached to the amplifier.
