(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. - Page 5 CAUTION: THE USE OF WIRE SMALLER THAN #8 GUAGE COULD DEGRADE AMPLIFIER PERFORMANCE AND CREATE A FIRE HAZARD Fig. 3 Power-Wiring Connections CMA-1 CONNECT GREEN REMOTE WIRE TO: Ignition Fuse Box Terminal Controlled By Key Fig. 4 Remote On/Off Wire Connection...
- Page 6 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 switched +12 VDC supply, either through the ignition key, the tape deck/tuner, or a switched terminal at the fuse box.
- Page 7 This unusual flexibility allows for 2-channel plus sub woofer, as well as other variations for custom installations. NOTE: The CMA-1 inputs are high-impedance line-level inputs. Speaker outputs from the car radio should NOT be wired into this amplifier. When connecting tuner/tape deck outputs to the CMA-1 inputs, use an appropriate connector, or solder the connections and insulate them with electrical tape.
