SM-SA604 4-CHANNEL CAR AMPLIFIER Instruction manual 4-
Your new high-fidelity bridgeable/stereo amplifier is designed to deliver maximum enjoyment and one year of trouble-free service.
Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or other critical parts of your car when installed. Never operate the amplifier without the proper power and ground wire 10 gauge minimum. Never operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will blow instead of the wire burning up.
Installation MOUNTING: 1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1. 2. Once the location has been determined, remove the plastic decorative panels from left and right sides of amplifier then place the amplifier in position. Using a felt tip pen or pencil mark the four holes to be drilled for mounting. Never use the amplifier as a template for drilling. It is very easy to damage the amplifier surface in manner. 3.
Connections POWER SUPPLY AND REMOTE TURN-ON OF THE AMPLIFIER Note: Do not connect the plus terminals to the car battery before other connections, or it may occur short circuit. The gauges of power and ground cables should be enough for the amplifier demands at least 5.27 mm 2. Firstly connect the GROUND terminal to the battery negative pole. It is very important that the connection is fastened. Loose connection may cause malfunctions or interference noise or distortion.
Operation elements and in-/outputs SETTING THE INPUT AND SENSITIVITY The regulator for input sensitivity is used to adapt amplifier for each car radio or tape deck. Turn the volume control of your radio to central position and adjust the input-level control (3) and (4) Fig. 7, to produce a medium volume. This setting can provide sufficient power and optimum Signal to Noise (S/N) ratio. Caution: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be damaged.

An on/off switch should be inserted in this case. Make sure that this switch is turned off if the amplifier is not used. Fig.
Fig.2. 4-channel mode Connect and set the amplifier as shown in Fig. 2, when the stereo has four outputs and the unit is used to drive four loudspeakers.

Fig. 3/4. 3-channel mode In the 3-channel mode, use high pass filter to regulate channels 1/2 and use low pass filter to regulate channels 3/4. Chapter Operation elements and in-/outputs describes how to set the filters. Connect and set the amplifier as shown in Fig.
FIG. 4 Connect and set the amplifier as shown in Fig. 4 if the system has two stereo outputs and one car radio output and is used to drive two stereo satellite loudspeakers and a subwoofer. (1) To the car radio, left output (4) Left satellite loudspeaker (2) To the car radio, right output (5) Right satellite loudspeaker (3) To the car radio, subwoofer output (6) Subwoofer Fig.
Fig. 5. 2-channel mode If the amplifier needs high power output to drive two subwoofers, connect and set it as shown in Fig. 5. The usage of the low-pass filter is described in Operation elements and in / outputs chapter (1) To the car radio, left output (3) Subwoofer (2) To the car radio, right output (4) Subwoofer Fig.
Fig. 6. Use the amplifier to drive four satellite loudspeakers and a subwoofer with using an additional 2-channel amplifier (1) To the car radio, front left output (2) To the car radio, front right output (3) To the car radio, rear left output (4) To the car radio, rear right output (5) Front left loudspeaker (6) Front right loudspeaker (7) Rear left loudspeaker (8) Rear right loudspeaker (9) Subwoofer Fig.
