1. RRCCAA  OOuuttppuutt  JJaacckkss - These pass

through RCA jacks can be used to
send a signal to a second amplifier.

2. RRCCAA IInnppuutt JJaacckkss - Accepts line level

outputs from head units or signal
processors at voltages between
150mV and 8 volts.

3. SSttaattuuss  LLEEDD - Will light GREEN to

indicate the amplifier is on and
operating normally and will be off if
the amplifier shuts down due to
short circuit, DC offset, or over-
heating detected by the on-board
protection circuitry.

speaker load, the more heat is
generated. For low impedance
speaker applications or restricted
ventilation installations, an external
cooling fan may be advisable.

9. Battery and ground connections to

the vehicle should be made with
crimped ring terminals of the appro-
priate size (surface area is what
counts); soldering the terminals
after crimping is also recom-
mended.

10. Due to the high-frequency MOSFET

switching power supply, filtering the
power cable is not generally
required (remember that the amp
can’t deliver full output if the power
supply is restricted). Proper
grounding of the signal source is
mandatory for the amplifier to
reach its performance peak.  If the
RCA inputs are not grounded
adequately via the signal source,
electrical noise from the vehicle
may be picked up in the system.
