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. 

 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.

Congratulations!
By purchasing an amplifier from MB Quart, you have decided on a product 
of the highest technical quality. MB Quart wishes you great enjoyment with 
your amplifier. Should you  have any questions about this system or other
