SAFETY

Make sure to pay attention to the instructions when you see this symbol:
Make sure that your vehicle has a 12 VDC voltage negative ground system, that it can
handle an increased power consumption.
Keep the cables inside the vehicle separate from sharp edges or components that may
be affected or take damage. Follow the recommended cable sizes and always use high
quality cables and accessories. Even if you are eager to put the amplifier to use – take
no shortcuts when installing the cables, make sure that all connectors are protected
and secured, and take your time finding the perfect grounding point.
Don’t drill any holes without checking what lies beneath, and don’t cut anything
without making sure that no important components risk being damaged.
There’s a first time for everything, if you need help - ask a friend or contact your local
GAS AUDIO POWER dealer/installer.
We want you to experience your products to the MAX, but we don’t want you to injure
yourself or others. Use common sense, respect high pressure levels and volume, and
follow your local laws and regulations.
NO COMPROMISES! Especially when it comes to safety. Before installing your MAX
EQ2 series equalizer, make sure that you read through the manual thoroughly and
follow the instructions. Save the manual for future usage and reference!

A well-built sound system will set you aside from the rest and elevate your vehicle! It’s
important that you carefully read the instructions on the following pages. This is to make
sure that you install and use the equalizer correctly, for the true MAX EXPERIENCE!
INSTALL EQUALIZER
HOW TO
Make sure your vehicle is up to task. You need a 12VDC negative ground electric system
and the power source and the alternator should be fully functional and healthy.
Disconnect and secure the negative terminal from your
power source to eliminate the risk of damaging your-
self or the products. Place the negative terminal in a
secure position so that it won’t accidentaly contact
the positive or the negative power source post.
Have all the necessary tools ready and close at hand. Make sure that the needed wiring
accessories are prepared. Your wiring kit should be of the recommended size stated in
this manual (see the SPECIFICATION chapter).
Find the perfect location to place your equalizer! The EQ2 equalizer can be mounted next to
your head unit or under the dashboard using the included mounting brackets. Always use
great care when attaching a new product to your vehicle - Check clearances in front, behind
and on both sides of the planned installation spot before drilling any holes or installing any
screws. Use a Phillips-head screwdriver to mount the unit. The front panel controls should
be easily accessible from the driver’s seat.

10
HOW TO
Find the best way to run the cables through your vehicle! This might take some time, and may
vary between different models. Preferably the cables shouldn’t be visible when you’re
finished and they shouldn’t be placed in a way that they obstruct any of the vehicle’s
functions or hinder you from operating the vehicle safely. It’s also important you don’t run
the power cable together with the signal cable, since this can cause interference. Make sure
to use high quality signal cables to avoid noise problems.
Always make sure that your full concentration is on the road while you drive. Do not
make advanced adjustments on your equalizer’s settings while driving.

HOW TO
EQUALIZER SETTINGS
SETTING THE SYSTEM VOLUME
AUTO TURN ON - ATO
Auto turn on function starts the unit, when a Hi-level (Speaker signal) is connected to either
MAIN or AUX-inputs. Even if you are paired with your mobile device the unit will start if
connected as above. To use the Auto turn on function, you need to use this type of cable:
ADJUST THE BAND SETTINGS
1. Set all frequencies to center position. The mark on the knob should be at 12 o'clock.
2. Play your favorite music, adjust the controls so it suits your taste.
Note: Stay away from extreme settings, this can lead to distortion in th music.
3. Adjust the equalizer gain control to suit your style.
4. If your system includes a subwoofer, slowly increase the sub level until you get the correct
bass level.
5. If your system includes rear speakers, adjust the fader control to add or subtract the level
of the rear system
1. Turn the master volume and subwoofer level controls to minimum on GAS EQ2.
2. Turn the source unit on (OEM Stereo) and increase the volume to approx. 70% of full volume.
3. Turn up the master level on the GAS EQ until you hear distortion. Normally 50% is a good
value (Straight up).
4. Reduce the volume to just below the distortion level.
This is the maximum usable musical signal for the source unit (OEM Stereo). Turning the volume
beyond this point only increases noise and distortion without increasing the music.
Note! Once you set the source unit volume, do not change it. Always use the volume on the
equalizer as the master volume control. The GAS MAX EQ has most likely better electronic
components and a higher S/N than the OEM Source.

12
HOW TO
CONNECTING AUX-IN
1. Plug in the external player in the AUX RCA input. (Do not Play music yet).
2. Unpress the AUX button on the front panel, make sure the button is out.
Ready to receive input from MAIN input. (NOT AUX input).
3. Turn the master volume to normal listening level.
4. Play music from the external device.
5. Press the AUX button on the front.
6. Use a small flat head screwdriver to adjust the level adjustment on the top of the unit.
Make sure the AUX source matches the volume of the main source.
SETTING THE LOW PASS FILTER (LPF)
1. Set the adjustable knob to frequency (30-200Hz) of choice for your subwoofer system.
2. Adjust the subwoofer level until you get the desired level of bass.
CONNECTING BLUETOOTH
1. Start your sound system and the equalizer.
2. Browse Bluetooth devices on your mobile device and choose the MAX EQ2-9BT equalizer.
3. Set the volume on the mobile device to 75-90% of max (Depending on model). If you can hear
distortion, the level on the mobile device should be adjusted just below the distortion level.
4. Use Master Volume to adjust the listening level.

TROUBLESHOOTING
NO POWER, NO LIGHTS
• Use a multimeter to check the voltage on the 12V + terminal and REM in.
• Check the fuse on the power cable.
• Check the ground wiring. Use a multimeter to confirm 12V
DISTORTED SOUND
• The source unit may be set too high. Reduce the volume on the source.
• EQ gain controls may be set too high. Re-set the EQ controls to the center.
• Check the settings onthe amplifier, make sure that the gain/level is set accoring to the
instruction. Test so lower the gain/level, to hear if the distortion ends.
• Lower the EQ’s on the GAS MAX EQ.
• Check the speakers, it might be something wrong with the speakers. Too much EQ can
damage a speaker.
UNWANTED NOISE
• Check the negative grounding point, make sure that the surface is clean and have a pure
metal connection. (Ground loop-issues)
• Check that no signal cables are close to the power cables.
• Lower/turn off the Bass EQ function on the amplifier.
• Check your speakers.
NO SOUND
• Wrong input is selected. Press AUX on the front panel to change between Main/Aux input.
• Bluetooth is paired with a device. Unpair or disable Bluetooth on the mobile device.
• Check that all signal cables are correct connected.
• Check speaker wires.
• Check AUX GAIN on the top of MAX EQ
When all above is tested/looked over, and all is as it should be. Consult your local GAS AUDIO
POWER dealer.
