PLEASE NOTE:
Read the enclosed warranty statement before
installation.
Installation of the CMA-l is complex and should not be attempted by
anyone without the proper tools or knowledge. This amplifier is
intended for state-of-the-art mobile fidelity and requires state-
of-the-art installation methods for full benefits.
**CAUTION**
Because this amplifier can draw extremely large current from the
battery, the standard automobile charging system may not be
sufficient. Even With the engine running, the amplifier may draw
enough current to discharge the battery. The owner/operator
should consider installing a higher-amperage alternator and a
secondary battery. Power consumption is 73 amps DC maximum, 10-40
amps DC nominal at 12-14 VDC.
Use only a minimum size of #8 gauge stranded cable (#6
recommended) between the battery and the CMA-l, for both positive
and negative leads, with no splices. Thinner cable may overheat
and cause a fire. Thinner cable also reduces the l2VDC power
available to drive the unit, thus reducing total output power and
performance. Use of a cable smaller than #8 gauge could void the
warranty.
Number 6 gauge stranded cable is highly recommended for lengths
over 12 feet or with installations demanding the highest possible
performance from the amplifier. Use cable intended specifically
for automotive use.
