System Design
The success of any car stereo system relies on several factors, such as
the system design, execution of the installation, and system setup. Please
remember that any system is only as good as its weakest link.
Please remember that higher power systems are not necessarily useful
purely for high sound pressure levels, but also to establish a headroom
capability, to reproduce musical peaks cleanly without distortion.
REF4.50 / REF4.80 / REF1.800
Lower power amplifiers will clip earlier than their more powerful cousins,
and cause loudspeaker failure when overdriven, due to the harmonics
generated by a clipped signal, thus overheating voice coils.
Amplifiers should be mounted with the fins running horizontally for best
convection cooling, to minimize overheating. Purchase the best quality
RCA cables you can afford, for reliability and less engine noise
interference in the audio system.
It is highly recommended that the amplifier be mounted to a board of MDF
or other solid structure using the 4 mounting screws provided. Avoid
mounting the amplifier to metal as this can introduce noise and other
unwanted issues. When mounting the amplifier, ensure that it is mounted
HORIZONTALLY, as shown in the diagram above, for optimal heat
dissipation. Mounting amplifiers to speaker enclosures is not
recommended as this can cause damage to the amplifier components.
When choosing a location for mounting the amplifier, ensure that you
check for clearance from wires, gas tank, electrical devices and brake
lines etc.

Page 3: Installation Instructions General Instructions
INSTALLATION INSTRUCTIONS General Instructions General: Run the wiring so that RCA cables are at least 18“ away from power and speaker cables. Keep RCA cables away from electrical devices in the vehicle that can cause electrical noise, such as electric fuel pumps, emission control modules and other on-board electronic modules. Power and ground connections:(See table below) Use a sufficient gauge power cable and ground cable using the chart below as reference to what size wire you require. -

INSTALLATION INSTRUCTIONS Settings for Best Performance REF4.50 / REF4.80 General: At this point you are ready to get more specific on the settings for your amplifier. High Pass: -When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. -
Page 5: Trouble Shooting
The key to finding the problem in a misbehaving sound system is to isolate parts of that system in a logical fashion to track down the fault. Description of the Diagnostic system built into all MB Quart amplifiers The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel PROTECT LED lighting up under the following conditions: 1 - A short circuit on the loudspeaker leads. -
Page 6: Ref4.50 / Ref4.80 4-Channel Amplifiers
Here we show how to use the 4 channel amplifiers as a 3 channel unit by taking advantage of the mono bridging capability of all MB Quart amplifiers. In order to create a 2 channel system, simply follow the example to also mono bridge channel pair 1/2. -
