Frequently Asked Questions - MW1000A Musway

How to correctly connect the power of the subwoofer?

First disconnect the negative battery terminal. Connect the GND terminal to ground, then the +12V cable with a 25 A fuse placed within 30 cm of the battery. Finally, connect the REM wire or use automatic turn-on.

What type of fuse to use and where to place it?

Use a 25 A fuse (standard type). Place it on the positive power cable, within 30 cm of the battery positive terminal for safety.

How to adjust the low-pass filter?

Turn the LOW PASS potentiometer to adjust the cutoff frequency between 50 and 150 Hz. Choose a value suitable for your subwoofer to avoid midrange.

What is the phase switch (0°/180°) for?

It allows you to invert the phase of the signal to synchronize the subwoofer with other speakers. Try both positions and choose the one that gives the best sound in your vehicle.

What to do if the red LED lights up?

The red LED indicates overheating or short circuit. Reduce the volume, check speaker impedance, and ensure adequate ventilation. The protection circuit shuts off the amplifier until the issue is resolved.

How to connect the turn-on signal (REM)?

Connect the REM terminal of the amplifier to the remote control output (antenna or head unit). Otherwise, use the high-level inputs which enable automatic turn-on.

Can I use the high-level inputs if my head unit has no RCA output?

Yes, the subwoofer accepts high-level inputs (directly from speaker outputs). Use the provided cable and automatic turn-on will be activated by the audio signal.

How to adjust the bass boost?

Turn the BASS BOOST potentiometer to add up to 12 dB of gain at 45 Hz. Be careful not to overdo it to avoid distortion.

What are the exact dimensions of the subwoofer?

The diameter is 360 mm and the height is 120 mm (cylindrical shape). Allow enough space in the vehicle.

Where to install the subwoofer in the car for best performance?

Place it in the trunk or under a seat, making sure it is securely fixed and protected from vibrations. Point the speaker towards the cabin for optimal sound.

IMPORTANT NOTES PRIOR TO INSTALLATION

• This device is only suited for a 12 volt system with negative ground.
• Ensure that the input and output cables are sufficiently separated from the power supply cables. Otherwise, interferences may occur.
• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the amplifier depends on the quality of installation. Preferably consult an expert to install the system.
• Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat belts, gas tank or the like.

INTERCONNECTION

ATTENTION: Before you start with the installation, disconnect the ground connection from the vehicle's battery in order to prevent short circuits. Use the enclosed cable plug to connect each terminal.

First connect the GND terminal of the amplifier to an appropriate ground connection at the chassis. To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion.

Then connect the +12V terminal of the amplifier with the battery by using an appropriate cable including an in-line fuse. This fuse should be located very close to the battery; for safety reasons not more than 30~cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been accomplished.

CAUTION: Never use the high level inputs and the RCA inputs at the same time. This may damage the device seriously. Use the enclosed cable plug to connect each terminal.

INTERCONNECTION BY RCA INPUTS WITH TURN-ON SIGNAL (REM):

INTERCONNECTION BY HIGH LEVEL INPUTS WITH AUTO TURN-ON:

INPUT SENSITIVITY

Turn the INPUT LEVEL controller of the amplifier to the MIN position. Then turn the volume controller of the head unit to 80 - 90% of its full setting. Now turn INPUT LEVEL clockwise until you hear some distortion. Then turn back INPUT LEVEL slightly until you hear a cleaner sound.

VARIABLE BASS BOOST

By using the BASS BOOST controller you are able to increase the bass enhancement from 0 to 12 dB.
ATTENTION: Use the BASS BOOST wisely!

VARIABLE LOW PASS FILTER

Set the desired crossover frequency by using the controller LOW PASS. Thus to that only the frequencies below the chosen crossover frequency will be amplified and the subwoofer plays more precisely and efficient.

PHASE SWITCH

The PHASE switch allows to switch the phase from 0^ to 180^ to match the output signal with the vehicle's interior acoustic.

PROTECTION CIRCUIT

The PWR LED lights up green, if the amplifier is in operation.

The PRO LED lights up red, when the amplifier is overheated, or a short circuit occurs respective a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts down the amplifier automatically. The amplifier should work again properly after you have solved the problems.

Troubleshooting

• Check all connections for defects or short circuits and correct them.

• Provide sufficient cooling in the event of overheating and reduce the volume.
