System Planning
Proper system planning is the best way to maximize your amplifier performance.
By planning your installation carefully you can avoid situations where the perfor-
mance of the reliability of your system is compromised. Your authorized dealer
has been trained to maximize your system’s sonic potential. Your dealer is a
valuable resource in helping you with your system design and installation.
Speaker Requirements
Each channel of your amplifier can easily
drive 4Ωspeaker loads when used ion the
stereo mode. When a channel-pair is bridged,
the recommended minimum load impedance
is 3Ω for subwoofer use, and 4Ω for full range
operation. Although operation with lower
impedances is not likely to cause immediate
damage to the internal circuitry, the unit will
most likely overheat, causing the thermal
protection circuitry to shut down the amplifier.
When the chassis cools down, normal
operation will resume. Continuing to operate
the amplifier under these conditions is not
recommended and will reduce its life
expectancy.
Most speakers designed for car audio
operation are 4Ω impedance. Connecting
two such speakers in parallel will result in
a 2Ω nominal impedance, which is not
recommended for use with bridged
channels of your amplifier.
Symptom
Distorted output
(cont’d)
Poor bass response
Battery fuse blowing
Amplifier fuse blowing
Possible Cause
Speakers are blown
Speakers wired wrong
polarity causing cancellation
at low frequencies
Crossover set incorrectly
Impedance load to amplifier
too low
Short in power wire or
incorrect power connections
Fuse used is smaller than
recommended
Too much current being drawn
Short in power wire or
incorrect
Too much current being drawn
Fuse used is smaller than
recommended
Action to take
Check system with known
working speaker and repair
or replace as needed
Check speaker polarity and
repair as needed
Reset crossover referring to
the multi-cross crossover
configuration section of this
manual for detailed instructions
Check speaker impedance load,
if below 2Ω stereo or 4Ω mono
rewire speakers to achieve a
higher impedance
Check power and ground
connections and repair as
needed
Replace with proper fuse size
Check speaker impedance load,
it below 2Ω stereo or 4Ω mono
rewire speaker to achieve a
higher impedance and replace
with recommended fuse size
Check power and ground
connections and repair as
needed
Check speaker impedance load.
It below 2Ω stereo or 4Ω mono
rewire speakers to achieve a
higher impedance and replace
with recommended fuse size
Check power and ground
connections and repair as
needed
Replace with proper fuse size

Notes on the power supply
Connect the +12V power input lead only after all other leads have been connected.
Be sure to connect the ground wire of the unit securely to a metal part of the car. A lose
connection may cause a malfunction of the amplifier.
REMOTE: The unit is turned on by applying +12Volts to this terminal. This terminal
does not draw heavy current like the two power terminal so a thinner connecting wire is
acceptable. Standard 18 GUAGE is fine and the standard color is yellow. If the power
antenna wire is already in use, you can still splice into it. With this method, the unit will
turn on automatically with the radio. Use the power supply lead with a fuse attached
whose value is the same as original fuse.
Place the fuse in the power supply lead as close as possible to the car battery.
During a full power operation. Maximum current will run through the system. Therefore,
Make sure that the leads to be connected to the +12V and GND terminals of the unit
respectively must be larger than 10-Guage (AWG 10)
Symptom
No output
Audio cycles on and off
Distorted output
Possible Cause
Low or no remote turn-on
input
Fuse down
Power wires not connected
Audio input not connected or
no output from source
Speaker wires not connected
Speaker are blown
Thermal protection engages
when amplifier heatsink
temperature exceeds 90
Loose or poor audio input
Amplifier level sensitivity set
too high; exceeding maximum
output capability of amplifier
Impedance load to amplifier
too low
Shorted speaker wires
Speaker not connected to
amplifier properly
Action to Take
Check remote turn-on voltage
output at amplifier and correct
as needed
Check power wire integrity
and reversed polarity, repair a
s needed and replace fuse
Check power wire and ground
connections and repair of
replace as needed
Check input connections and
signal integrity, repair or
replace as needed
Check speaker wires and repair o
r replace as needed
Check system with known
working speaker and repair or
replace speakers as needed
Make sure there is proper
ventilation for amplifier and
improve ventilation as needed
Check input connections and
repair or replace as needed
Reset gain referring to the
turning section of the manual
for detailed instructions
Check speaker impedance load
if below 2 stereo or 4 mono Ω Ω
rewire speakers to achieve a
higher impedance
Check speaker wire
connections and repair or
replace as needed
Check speaker wiring and
repair or replace as needed
