Before you start
⚠ CAUTION ⚠
Many new and factory radios require a reset code when disconnected from
battery power. This is an anti-theft feature . Before unplugging power, you
must determine if your radio/source unit requires a reset code . Check the
operation
manual for your vehicle or contact the dealer.
Congratulations on your choice of a MBQuart amplifier. This “Quick Start Installation” guide is meant to help you “hook up” and play music. For more detailed information , on system setting , speaker and subwoofer configuration and full specifications by model please visit our website at www.MBQuart.com

Installation
Common System Setup
Setup
Open Control Panel
To gain access to the RA1 amplifier series top mount setting control panel carefully remove the four screws and lift the face plate up.
When you’re finished with the control panel mindfully put the face plate back together with the four screws. Make sure not to over tighten.
Settings
The illustrations below describe the various controls. Refer to the
illustration that matches your amplifier.
-
LEVEL Adjustment
The level control purpose is to match the output of your source signal to the amplifier. Refer to the section C for detailed instructions. -
X-OVER Switch
This switch will set the amplifier to have a full frequency output or to filter out high or low frequencies. -
Frequencies Adjustment
The Low Pass Filter will cut off the frequencies above the setting. The High Pass Filter will cut off the frequencies below the setting. -
SUBSONIC Switch
The Subsonic Switch will cut off the frequencies below the setting. -
BASS BOOST ⚠
The Bass EQ control will increase the power output at 45Hz for more pronounced bass. Exercise caution when using this control. Increase the level in small
amounts until distortion is noticed , then back off a little.
Level Setting ⚠
This is a critical step to insure your amplifier is properly adjusted to match
the signal output level of your source unit.
THIS IS NOT A VOLUME CONTROL!
- If possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).
- Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “O” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.
- Play a clean musical selection of which you are very familiar. CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
- Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.
- Increase the amplifier gain (clockwise) until distortion is heard, then back the level down (counter clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.
Remote Level Control
Some models include a bass remote. Avoid adjusting the bass remote while operating vehicle.
Turn on Mode
REM turn on SIGNAL SENSE ON, High level
Turn on Mode input DC turn on
REM TURN ON/ DC SENSE ON SWITCH
There are two methods of switching the amplifier on and off. Select the
appropriate position suited for your application.
REM TURN ON

source unit, is connected to the Amp Turn on – BLUE wire on the main power
connection harness.
DC SENSE
The DC SENSE is for use with the source units that do not offer RCA outputs.
⚠ NOTE – If the RCA’s are plugged into the amplifier and the TURN ON MODE is in the DC ON position, the amplifier will NOT turn on. Please re-read this document or hire a professional installer.
