It is very important to install a 60-amp fuse in the +12VDC power
wire at the battery. This fuse prevents fires caused by wiring
shorts to the vehicle chassis due to improper installation or
unforeseen accidents.
As in any professional installation, fusing the speaker lines is
highly recommended to protect the speakers. Refer to Figure 1 to
determine proper speaker-fuse values.
If speaker cables must be spliced to shorten or lengthen them, the
splices must be mechanically and electrically sound. Simply
twisting wires together and wrapping with electrical tape is not
adequate. We strongly recommend insulated crimped terminals, wire
nuts wrapped with electrical tape, or solder connections with wire
nuts wrapped with electrical tape.
Avoid pinching or piercing the speaker cable during installation.
Route speaker cables separate from amplifier- input cables to
prevent oscillations. Observe proper polarity of plus and minus
wires when adding wire.
Due to extreme output power, the CMA-1 could, when abused, damage
certain models of loudspeakers. Use speakers that can handle the
amplifier power output. After installation, turn up the volume
slowly and avoid overdriving the speakers.
Accessories Supplied:
60-amp fuse
Fuse Holder
Input cable harness
Remote on/off cable
Mounting: Mount the CMA-1 securely, say to the vehicle chassis or to a wooden panel. Allow
adequate airspace (at least 1") and sufficient airflow around the heat fins for cooling. The CMA-1
may be mounted horizontally or vertically in the trunk or behind rear car seats. DO NOT place the
CMA-1 in the engine compartment or in an area exposed to a harsh environment. Do not mount near
the vehicle heater.
Dimensions of the CMA-1 are 16"L x 14-1/2"W x 1-5/8"H. Mounting-hole locations are shown in
Figure 2. The amplifier can be used as a hole template.
**Caution**
The CMA-1 comes complete with:
