CAUTION: If you feel unsure about installing this system yourself, have it installed by a
authorized MB Quart Dealer.
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent
damage to the unit, fire and/or possible injury.
Before beginning any installation, follow these simple rules:
1. Be sure to carefully read and understand the instructions before attempting to install the unit.
2. For safety, disconnect the negative lead from the battery prior to beginning the installation.
3. For easier assembly, we suggest you run all wires prior to mounting your unit in place.
4. Route all of the RCA cables close together and away from any high current wires.
5. Use high quality connectors for a reliable installation and to minimize signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires
routed through metal, especially the firewall.
9. ALWAYS protect the battery and electrical system from damage with proper fusing. Install the appropriate
fuse holder and fuse on the +12V power wire within 18” (45.7 cm) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean
ground connection. Grounding connections should be as short as possible and always be connected to
metal that is welded to the main body, or chassis, of the vehicle.
MOUNTING LOCATIONS
Engine Compartment
Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void
your warranty.
Trunk Mounting
Mounting the amplifier vertically will provide adequate cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will provide the best cooling of the amplifier.
Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will
severely affect the performance of the amplifier and is strongly not recommended.
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of
air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you
must have at least 1" (2.54cm) of air gap around the amplifier's fan intake and top exhaust vents.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier in the passenger
compartment will not provide proper cooling and will severely affect the performance of the amplifier and is
strongly not recommended.
BATTERY AND CHARGING
Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking
your alternator and battery condition to ensure that the electrical system has enough capacity to handle the
increased load of your stereo system. Stock electrical systems which are in good condition should be able to
handle the extra load of any MB Quart amplifier without problems, although battery and alternator life can
be reduced slightly. To maximize the performance of your amplifier, we suggest the use of a heavy duty
battery and an energy storage capacitor.
