Frequently Asked Questions - Integration IBUS20 FOCAL

How to connect the Focal Integration IBUS20 subwoofer to a car radio without RCA output?

Use the high level input (HI LEVEL INPUT) with the supplied high level connector. Connect the wires to the speaker outputs of the car radio. The signal will be adapted automatically.

What does the red LED on the amplifier mean?

The red LED indicates the amplifier is in protection mode. This can be due to overheating, a short circuit, or faulty wiring. Check connections and ventilation.

How to adjust the bass level (gain) correctly?

The GAIN potentiometer adjusts the input level. Turn it gradually until you get a homogeneous sound level without distortion. Note: too high gain increases noise, not power.

What is the SUBSONIC filter for?

The SUBSONIC filter (high-pass) cuts very low infra frequencies that could damage the speaker. Set it between 20 and 50 Hz according to your front speakers.

How to connect the REM (remote) wire?

The REM wire (blue) must be connected to the REMOTE output of the car radio. It allows automatic power on of the subwoofer when the car radio turns on.

Can I use the subwoofer without connecting the remote wire?

Yes, if you use the high level inputs, activate the AUTO POWER ON function (ON mode). This detects the audio signal and turns on the amplifier automatically. Does not work with RCA inputs.

How to choose the position of the PHASE selector?

Listen to music with bass and switch the selector between 0° and 180°. Choose the position that gives the most bass. This synchronizes the subwoofer with the front speakers.

What fuse to use for replacement?

Use a fuse of the same amperage as the original (usually 20A). Check the value on the FUSE connector. An oversized fuse can damage the device.

The subwoofer does not turn on, what to do?

Check the power connections (+12V, GND and REM). Check the vehicle's main fuse and the amplifier's fuse. If the LED is off, the problem is likely electrical.

How to clean and maintain the subwoofer?

Use a soft dry cloth to dust. Avoid moisture and chemicals. Make sure connections remain clean and tight.

① + 12V : The ^+ BATT power supply connector is dedicated to receiving the power supply cable ensuring the link between the amplifier and the positive (+) terminal of the battery.
② GND: The GND power supply connector (ground) is dedicated to receive the negative power supply wire linking the amplifier and the vehicle chassis.
③ REM: The REM connector ensures the link between the IBUS 20 and the source (the car radio) via a REM or REMOTE output of the car radio. It permits to automatically switch on the amplifier as soon as the source (the car radio) is turned on.
④ HI LEVEL INPUT: The HI LEVEL INPUT terminal permits to connect the car radio to the amplifier via the car radio speaker outputs and the high-level connector supplied in the packaging.
⑤ INPUT: The RCA sockets permit to convey the low level signal of the head unit to the amplifier.
⑥ FUSE: The FUSE connector is dedicated to receive the fuse(s) of the amplifier. In case of replacement, make sure of the perfect conformity of the amperage.
⑦ REMOTE CONTROL PLUG: the REMOTE CONTROL connector is dedicated to the wiring of the remote control supplied.
GAIN: The GAIN rotary potentiometer permits to adjust the signal level coming in the amplifier. CAUTION: increasing the input gain doesn't mean more power, but more noise. The tension gain varies from 0.2V to 5V.
SUBSONIC: The SUBSONIC rotary potentiometer permits to set the high-pass filter value. The chosen value defines the frequency from which the signal is amplified.
10 BASS BOOST: The BASS BOOST rotary potentiometer permits to increase the bass level from 0 to +18dB. The central frequency is 60Hz.
⑪ LO PASS: The LO PASS rotary potentiometer permits the setting of the low-pass filter value. The selected value defines the frequency until which the signal is amplified.
PHASE: The PHASE selector permits to adjust the phase setting of the bass channel according to the installation. To determine the correct position of this inverter, simply check if it provides the maximum of bass frequencies.
13 Auto Power On: In ON mode, it's not necessary to connect the remote cable if you're using the high level inputs. Do not function with the RCA inputs.
⑭LED: The light indicator permits to check the correct working of the amplifier. When the LED is green, it means the amplifier is on and it's working correctly. WHEN the LED is red, it means the amplifier is in protection mode following a dysfunction (overheating, wrong wiring, ...).
