INSTALLATION
The Road Thunder Sound Bar Plus can be used with any 12-volt battery and can be mounted to a variety of bars using the included
hardware. The unit has four wires in its wiring pigtail. The red wire, hot, should be directly connected to the vehicles positive battery
terminal. The black wire, ground, should be connected directly to the vehicle’s chassis where paint has been removed or the negative
terminal on the battery. Use the included T-Tap Quick Connect Female connector and install directly onto the ACC/Key ignition wire
on the motorcycle using a pair of pliers. Connect the Quick Connect Male connector, located on the orange wire, and the T-Tap Quick
Connect Female together. The blue wire, optional output, can be used to turn on additional ampliers.
The unit features fully adjustable clamps for mounting to bars between 7⁄8” and 1-1⁄2”. The clamps can be used to mount to many
styles of handlebar and roll bar systems. The included brackets are versatile, so mounting to angled bars is possible.
SCENARIO 1
-
MOUNT CLAMPS TO HANDLEBAR FIRST, THEN INSTALL SOUND BAR.
• Choose the correct size strap clamp for the handlebars.
Note: placing the transparent lm between the strap clamp and handlebar will reduce the possibility of scratching the handlebars
during installation.
• Assemble mid-section to bottom bracket using included 5mm Allen screw and 10mm hex nut.
• Ensure that the spacing between the brackets is between 3” and 6.75”.
• Slide the sound bar into the brackets from the left side, so the brackets can clear the buttons without damaging them.
• Rotate the sound bar so the speakers are directed at the rider’s head.
• Tighten the 5mm Allen screws to lock the sound bar in place.
• Tighten the 2mm set screws.
• Connect wires to power, ground, and ignition.
