High-powered car audio
systems may produce
sound pressure levels that
exceed the threshold at which hearing
loss may result.
They may also impair a driver’s ability to
hear traffic sounds or emergency vehicles. Use common sense and practice
safe listening habits when listening to or
adjusting your audio system.

INSTALLATION GUIDELINES
1. Please read this owner's manual care-
fully before installing this amplifier.
2. Disconnect the battery ground
terminal prior to making any electrical connections.
3. Check for any hazards or obstruc-
tions such as gas tanks, fuel or
brake lines, and wiring harnesses
before mounting the amplifier.
4. Pick a mounting location that will
provide adequate access and ventilation and protect the amplifier
from heat, moisture, and dirt.
5. Avoid sharp metal areas when
routing cables to the amplifier, and
run RCA cables away from the
power cables and other potentially
noisy car harnesses.
6. The amplifier should be grounded
with a short, heavy gauge wire
connected directly to the car at a
bare metal surface, preferably
scraped body sheet metal. Do not
use factory grounded locations,
seat bolts, or brackets that are
spotwelded.
7. Always fuse your power connection
within in 8 to 10 inches of the
battery terminal. Use a fuse or
circuit breaker rated slightly more
than the on-board fuse(s) of the
amplifier(s). The gauge of power
wire used should take into account
the total current draw of the
system, and the length of the wire
used. IASCA and other auto sound
competition organizations have
charts available for this; you can
also find a chart in the MECP study
guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification
Prior to servicing your vehicle ensure
that the alarm system is
ddiissaarrmmeedd
. Due
to the amplifier’s anti-theft feature (if
enabled), amplifier operation is disabled
when the main power to the amplifier is
removed while the alarm is armed. The
amplifier operation must then be reset.
If the alarm is replaced with another
ESP2 alarm system, ensure that the
amplifier goes through a learn routine
(using the Bitwriter
®
) prior to re-
enabling the anti-theft feature.

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 necessary, upgrade it by adding an additional 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 appropriate 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.
