POWER WIRING: (refer to Figure 3)
1. Before beginning installation, disconnect the Positive (+) battery power cable. Do not re-
connect the power cable until installation is complete.
2. Using only the minimum size #8 stranded cable (#6 recommended) with a terminal on the
battery end, connect the CMA-1 terminal marked “-“ to the negative (-) terminal of the
battery. Do not splice the cable.
Connecting this cable anywhere other than the battery is
not acceptable
(i.e., don’t connect to the vehicle fuse block because the CMA-1 current
draw could melt the vehicle’s wire harness!)
3. Using ONLY the minimum size #8 stranded cable (#6 recommended) with a terminal on the
end, connect the CMA-1 terminal marked “+” to the positive (+) battery cable terminal you
just removed. Do not splice the cable (except for the fuse holder).
Connecting this cable
anywhere other than the battery is not acceptable
.
If you’re using the same cable for both the positive and negative connections, clearly mark
the positive cable to prevent miswiring. Improper connection could damage the amplifier,
battery or electrical system.
4. Install the supplied 60-amp fuse in the Positive (+) cable near the battery. Failure to install
the fuse could result in vehicle fire due to accidental shorting of the power cables.
REMOTE ON/OFF WIRING
(Refer to
Figure 4
)
1. Turn down your sound system volume to minimum.
2. The green “remote” wire on the CMA-1 is, in effect, the on/off switch of the amplifier.
Connect the green remote wire to the sw12 VDC supply, either through the ignition
key, the tape deck/tuner, or a switched terminal at the fuse box. Some tuners have a switched
+12v terminal for this purpose.
Do not confuse the green remote wire with the green speaker wire (see
Figure 4
).
DO NOT connect the green wire to the main +12VDC power supply lead or other
continuously “hot” sources; this will cause the amplifier to be continuously on and will drain
the battery.
3. DO NOT turn on the power until the speaker cables are installed (described later)
