1. Gain Adjuster – These can be adjusted to match output levels from a variety of source units individually

for the front and rear inputs.

2. Crossover Multiplier Range Switch – Used to set the multiplier for the left and right crossover

frequencies between x1 and x10. A setting of x1 leaves the adjustable crossover frequency from

50-500Hz. A setting of x10 changes the adjustable crossover frequency to 500-5KHz (5000Hz)

3. Crossover Frequency Adjuster– Used to adjust the front and rear crossover frequency. Variable from 50Hz

to 500Hz in x1 mode, and 500-5KHz in x10 mode.

4. Crossover Type – Is used for selecting High-Pass Filter (HPF) or Low-Pass Filter (LPF) operation for the

front and rear speaker outputs.

5. Crossover Filter Switch – Off sets the crossover to all-pass, adjustments to the crossover range, freq, and

type are bypassed. On allows adjustments to the crossover settings to be used.

6. Front End Defeat – Used to reroute the input signal around the signal processing circuitry within the

amplifier. While in the ON position, all gain and crossover functions are bypassed.

7. Clipping LED Indicators – These Yellow LEDs illuminate if clipping is detected for either the front or rear

channel outputs.

8. Power LED – This Green LED illuminates when the unit is turned on.

9. 2/4 Channel Switch – Pressing this switch in, switches the inputs to a 2-channel mode, allowing

connection to only the front inputs with a 4-channel output.

10. Protect LED – This Red LED illuminates if a short circuit or too low of an impedance is detected at the

speaker connections or if the amplifier reaches thermal protection. The amplifier will automatically shut

down if this occurs.

INST

ALLATION

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.

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.

5. Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable. Use the

ring terminal to connect to the battery positive terminal.

6. Prepare the BLACK wire (Ground 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. Prepare the vehicle chassis ground by scraping any paint from the metal

surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and attach a

ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer.

NOTE: Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30"(76.2cm).

7. Prepare the Remote turn-on wire by stripping 1/2" of insulation from the end of the wire. Insert the

bared wire into the “R” terminal on the plug connector. Tighten the set screw with a 3/16" allen wrench

to secure the cable in place. Connect the other end of the Remote wire to a switched 12 volt positive

source. The switched voltage is usually taken from the source unit's accessory lead. If the source unit

does not have this output available, the recommended solution is to wire a mechanical switch in line

with a 12 volt source to activate the amplifier manually.

ALLATION

8. Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier on

cardboard or plastic panels. Doing so may enable the screws to pull out from the panel due to road

vibration or sudden vehicle stops.

9. Connect source signal by plugging the RCA cables into the input jacks at the amplifier.

CAUTION: Always ensure power is off or disconnected at the amplifier before connecting

RCA cables. Failure to do so may cause injury, damage to the amplifier and/or

connected components.

10. Connect the speakers. Strip the speaker wires 1/2" and insert into the speaker plug connector and tighten

the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis ground

any of the speaker leads as unstable operation may result.

11. Perform a final check of the completed system wiring to ensure that all connections are accurate. Check

all power and ground connections for frayed wires and loose connections which could cause problems.

12. Ensure the amplifier is mounted securely and reinstall the end cover. Install an inline fuse near the

battery connection.

NOTE: Follow the diagrams for proper signal polarity.

CAUTION: These amplifiers are not recommended for impedance loads below 2 stereo

and 4 bridged.

CAUTION: Do not attempt to connect the source units speaker leads directly to the RCA

connections of this amplifier, as damage to the source unit and/or the

amplifier may result.
