MA-4BT Installation Instructions
Step #1: The main parts of the kit are: speaker cabinets, clamps/collars, “control box” ,
threaded ball for control box, and wire harness . Please identify before proceeding.
Step#2: Without attaching anything yet, plan where each component will go on the
machine. For best sound, assuming this kit is going on a motorcycle, the speakers
should be placed even distances from the center of the handlebars and aimed directly at
the riders ears. Speakers mounted behind a windshield will sound better and be louder
for the rider. Mount the speakers to crash bars only as a “last resort”. The control box
can be mounted anywhere on the bars, but careful consideration must be given to the
operator safely adjusting the control buttons while the machine is still or in motion.
Step#3: Using the supplied clamps: The kit comes with “collars” that adapt the handle-
bar clamps to fit 7/8”, 1”, or 1.25” diameters and only fit one way. As shown below, the
screw that must be used closest to the ball socket is the longer of the 2 supplied screws.
Place the clamp halves over the bars, and get the nuts started on the screws.
If not already installed, screw the “threaded balls” into the
back of the speakers and the location on the main control box
that works best for you. NOTE: Your kit comes with 1” thread-
ed “standoffs” that can give more options for mounting. Using
“BLUE” thread lock material will help keep things secure.
Once you have the screws on the clamps started, and the
speakers or control box sitting how you like it, tighten the long
screw closest to the ball socket FIRST. This will secure the ball
to the socket best. Once the top (longer) screw is tight, tighten
the shorter screw at the bottom of the clamp. This will
properly tighten the clamps to your bars.
If the supplied clamps will not work for your application, the threaded balls on the
speakers unscrew, exposing a standard 1/4-20 thread pattern which allows the use of
Ram® Mounting systems or other custom mounting.
IMPORTANT: The thread length
going into control box must not exceed 1/4” (7mm). The thread length going
into speaker cabinets must not exceed 3/4” (20mm)
