Kenwood KSC-WA80 Instruction Manual

If your Kenwood KSC-WA80 subwoofer is not working, refer to the Troubleshooting Guide. If there is no sound, follow these steps:

• Check if sound is heard from the rear speakers. If not, check the car's ignition switch, the fuse in the car body, and the Center Unit (cassette receiver, etc.).
• If sound is heard from the rear speakers, check if the KSC-WA80's indicator blinks. If it does, check the INPUT SENSITIVITY Switch of the KSC-WA80, the fuse of the KSC-WA80, and the power supply cords connections of the KSC-WA80. If the indicator does not blink, check the Input connections of the KSC-WA80.

If the sound level is too low or high, adjust the input sensitivity adjusting knob to the correct position. If the sound quality is bad or distorted, check if a speaker cord is pinched by a screw in the car body and inspect the speaker wiring.

Recommended audio settings depend on the size of your rear speakers. Use the following table as a reference:

• Large Rear Speaker: Turn over Frequency at 50 Hz, Input Sensitivity at MIN, Phase at 0°.
• Medium Rear Speaker: Turn over Frequency at 80 Hz, Input Sensitivity at MIN, Phase at 0°.
• Small Rear Speaker: Turn over Frequency at 200 Hz, Input Sensitivity at MAX, Phase at 180°.

Additionally, you should adjust the low frequency level by turning the knob to the desired level, and adjust the low frequency phase by setting the PHASE switch to either 0° or 180° according to your liking and the unit's position or orientation.

Wiring diagrams for the Kenwood KSC-WA80 can be found in the "Connections / Anschlüsse" section of the manual, specifically on page 4 and page 5. These pages provide various application examples for connecting the subwoofer to your car stereo system.

No, the Kenwood KSC-WA80 is a Powered Subwoofer, meaning it has a built-in amplifier and does not require an external one. It has a Max. Power Output of 50W/Ω + 50W/Ω (Dual Voice-Coil Drive) and a Rated Power Output of 30W/Ω + 30W/Ω (Dual Voice-Coil Drive).

When installing the Kenwood KSC-WA80, avoid unstable locations or places subject to dust, direct sunlight, excessive heat, or humidity. The unit should be secured to the car chassis to prevent rattling. One recommended method is to place a wooden plate with sufficient thickness and size below the floor carpet and attach the provided fixing hardware and belts to secure the unit.

To connect the Kenwood KSC-WA80 subwoofer, first ensure you remove the negative (-) cable from the car battery to prevent electrical shorting before beginning the connection procedure. The unit can be connected in several ways to enhance the bass sound of your car stereo system:

• General Connection: Connect the subwoofer to your center unit (e.g., cassette receiver) and front/rear speakers. Figure 1 illustrates this setup.
• Connection with two KSC-WA100/WA80 units: If you have two units, they can be connected together. Figure 2 shows this configuration.
• Connection to an additional power amplifier: The subwoofer can be connected to an external power amplifier. Figure 3 and Figure 4 provide diagrams for these connections.
• Connection to an audio equalizer unit: You can also connect the subwoofer to an audio equalizer unit, such as a graphic equalizer. Figure 5 details this setup.

After all connections are made, double-check them for correctness before reconnecting the negative (-) cable to the car battery. Ensure the unit is fastened securely and not exposed to excess vibration.

The Kenwood KSC-WA80 is designed to connect to a car's "CENTER UNIT" (such as a cassette receiver) and includes both RCA Pin Jack and Speaker input terminals, allowing for various connection methods. It is generally compatible with car stereo systems that provide these standard output options.

The Kenwood KSC-WA80 subwoofer's power supply turns "ON" when the power indicator lights in red, and turns "OFF" when the indicator goes out. The unit is connected to the car's ignition key switch and a power control output terminal from the center unit, which manages its power state.

The Kenwood KSC-WA80 comes with a Power Supply Cord and a Speaker cord (4.5 m) as part of its included parts.

If a buzzing noise is heard from the speakers when the engine is running, you should attach a line noise filter (sold separately) to the power lead.

To adjust the low pass filter settings, use the LOW PASS FREQUENCY control knob. Turn this knob to adjust the balance between the bass from the rear speakers and the bass from the KSC-WA80 to your desired level. The adjustable frequency range for the KSC-WA80 is 80~300 Hz.

Yes, the Kenwood KSC-WA80 is a Powered Subwoofer.
