1. EESSPP ® ® PPoorrtt -- connection port for
Bitwriter ® or ESP2 security system.
2. EESSPP ® ®

functionality and is used to diag-
nose ESP
® features.
3. RRCCAA IInnppuutt JJaacckkss - accepts line level
outputs from head units or signal
processors at voltages between
250 mV and 7.5 volts. (A1004
and D2205 also have a Rear
Input.)
4. RRCCAA OOuuttppuutt JJaacckkss - these pass
through RCA jacks can be used to
send a signal to a second amplifier.

page. Always use the same gauge
wire for the amplifier ground that
you use for the power wire. Be sure
to examine the battery ground
cable of the vehicle, and if neces-
sary, upgrade it by adding an addi-
tional ground wire that is the same
gauge as the amplifier's power
wire. Remember, the amplifier can
only deliver its rated output when it
is not current limited by the power
and ground supply wires.
8. This amplifier is designed to drive a
speaker load that measures from 2
to 8 ohms (1 ohm on D2205 Sub
Output). Keep in mind that heat is
the long-term enemy of automotive
electronics and the lower your
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 recommended.
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.
