Frequently Asked Questions - Quantum Q800A ESX

How to connect the amplifier?

First connect the GND terminal to the negative ground of the battery. Then connect the +12 V terminal via a cable with an integrated fuse to the positive terminal of the battery. The fuse must be placed within 30 cm of the battery. Make sure all connections are tight.

Which fuse to use for the amplifier?

Use a 20 A fuse placed near the battery on the +12 V power cable.

How to adjust the Bass Boost?

The BASS BOOST control increases bass level by 0 to 12 dB at 45 Hz. Use it moderately to avoid distortion.

What to do if the sound is distorted?

First check the input level setting (INPUT LEVEL). Make sure the input sensitivity matches your car radio. Reduce the gain or Bass Boost if needed. Also check that connections are correct and the fuse is not defective.

Can I use this amplifier with a 24 V battery?

No, the amplifier is designed for a 12 V system (range 9-15 V). Higher voltage could damage the unit.

How to adjust the input sensitivity?

First set your car radio volume to a medium level. Then turn the amplifier's INPUT LEVEL potentiometer to achieve a comfortable listening volume. This ensures an optimal signal-to-noise ratio.

What is the phase switch for?

The PHASE switch toggles between 0° and 180° to synchronize the subwoofer's response with the other speakers in the vehicle, depending on the acoustic characteristics of the cabin.

How to clean the speaker?

Use a dry, soft cloth to dust the surface. Avoid any liquid or chemical that could damage the membrane.

Can I install the device myself?

It is recommended to have the installation done by a specialist to avoid damaging vehicle components (cables, onboard computer, fuel tank, etc.) and to ensure optimal safety.

What is the warranty on the product?

Warranty depends on the retailer. Check the warranty terms provided with the device or contact ESX customer service.

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.
