ALLATION
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.
WIRING THE SYSTEM
CAUTION: If you do not feel comfortable with wiring your new unit, please see your local
authorized MB Quart Dealer for installation.
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent
damage to the unit, fire and/or possible injury.
CAUTION: Avoid running power wires near the low level input cables, antenna, power
leads, sensitive equipment or harnesses. The power wires carry substantial
current and could induce noise into the audio system.
1. Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power cables and
any high power auto accessories, especially electric motors. This is done to prevent coupling the noise
from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any
metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires
long at this point to adjust for a precise fit at a later time.
2. Remove the four (4) 8/32 allen head screws holding
the connection end cover in place (this is the end
without the vents for the fans). Keep the cover and
screws in a safe place for reinstallation when
mounting and wiring is complete.
3. Prepare the RED wire (power cable) by stripping
1/2" of insulation from the end of the wire. Insert
the bared wire into the “+” terminal on the plug
connector. Tighten the set screw with a 3/32" allen
wrench to secure the cable in place.
NOTE: The "+" (positive) cable MUST be fused 18" or
less from the vehicle's battery. Install the
fuseholder under the hood and ensure
connections are water tight.
4. Trim the RED wire (power cable) within 18" of the
battery and splice in a inline fuse holder. See
Specifications for the rating of the fuse to be used.
DO NOT install the fuse at this time.
