The CS subwoofer amplifier is a single-channel amplifier. There are two sets of terminals to make it easy to connect multiple woofers. Either set of (+/–) terminals may be used when connecting woofers. To the right are two application diagrams to help plan your subwoofer system installation. Figures 2 and 3 show how to configure the CS200.1 subwoofer amplifier. NOTE: For simplicity, Figures 2 and 3 do not show power, remote and input connections. NOTE: Minimum speaker load is 2 ohms total. Figure 2. CS subwoofer amplifier with two woofers connected. Figure 3. CS subwoofer amplifier with one woofer connected. Figure 4. CS60.4 amplifier in 4-channel (stereo) operation to drive front and rear full-range speakers. Figure 5. CS60.4 is set up for 3-channel operation to drive a set of full-range speakers and a subwoofer. Figure 6. CS60.4 used in bridged 2-channel mode to drive a set of components or subwoofers. Set crossovers according to application. APPLICATIONS – CS60.4 The CS60.4 can be set up for stereo 4-channel, 3-channel or bridged 2-channel operation, as shown in Figures 4 through 6. NOTE: For simplicity, Figures 4 through 6 do not show power, remote and input connections. NOTE: Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms. CS Series 60.4 3

CONTROLS AND SETUP SYMPTOM LIKELY CAUSE SOLUTION No audio No voltage at BATT+ Check voltages at (POWER LEDs or REM terminals, amplifier terminals are off) or bad or no ground with VOM connection No audio Amplifier is Make sure amplifier (POWER overheated cooling is not blocked LEDs are on) at mounting location; verify speaker-system impedance is within specified limits Voltage more than 16V Check vehicle or less than 8.5V on charging system BATT+ connection SYMPTOM LIKELY CAUSE SOLUTION No audio Voltage less than 9V on Check vehicle (POWER BATT+ connection charging system LEDs flash) DC voltage on Amplifier may need amplifier output service; see enclosed warranty card for service information Distorted audio Input sensitivity is Check INPUT not set properly, or LEVEL setting; or amplifier or source check speaker wires unit is defective for shorts or grounds Distorted audio Short circuit in Remove speaker leads and POWER speaker or wire one at a time to locate LEDs flash shorted speaker or wire, then repair Music lacks Speakers are not Check speaker “punch” connected properly connections for proper polarity SETTING THE CROSSOVER(S) Determine your system plans and set the crossover mode switch accordingly. If your system design does not include a subwoofer with the CS60.4, set the crossover mode to FLAT and skip to “Setting Input Sensitivity.” Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible. Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. Adjust the crossover frequency to limit bass and provide increased system volume with less distortion. For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer. If using the CS60.4 to drive a subwoofer(s), set the crossover mode to LP (low pass). SETTING INPUT SENSITIVITY 1. Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise). 2. Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track. 3. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard. NOTE: After the source unit is on, blue LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to “Troubleshooting” guide below. TROUBLESHOOTING CS Series 60.4 4
