CH1-CH5 RCA’s: RCA signal from source
CH1-CH5 SPEAKER OUTPUTS- This is where your speakers plug in, see the amp specific
diagrams for assistance.
GAIN- NOT A VOLUME KNOB, THE INTERNET IS LYING TO YOU 😊, used
to set the input signal levels, start from Min and slowly turn clockwise until you
hear angels singing or the sirens from the cops looking for you. Scan this QR
Code for a video on setting your gains.
CROSSOVER-
HP- Sets the crossover to only use the High pass filter.
FLAT- Turns off the crossover filters (Warning, only use if you have external passive or active filters,
not using filters can damage your speakers.
LP/BP- Sets the crossover for Low pass filter, can also be used for Bandpass.
HIGH - High pass filter, used to set max high-level frequency.
LOW- Low pass filter, used to set the minimum low-level frequency.
BOOST (LEVEL)- Often called BASS BOOST, increases the 50Hz signal.
PWR –Power LED, if it’s on, your good, if its off, you’re not good. See the troubleshooting section if it doesn’t
turn on.
CLIP- Clipping LED, if this is flashing or solid you could damage your speakers, turn down your gain.
PRT- Protect, the amp is in protect mode, see the troubleshooting section for assistance.
Note- The PWR, CLIP, and PRT leds will flash as a test when the amp is first powered on.
REMOTE- Plugin for the external bass knob, used to attenuate the from lowest point to the highest that was
set on the amplifier

SAEv4 SERIES AMPLIFIER OWNER’S MANUAL version 1.1
+12V Battery
You need to connect a power wire to the vehicle’s positive battery terminal. This connection must be tight and
secure to ensure proper connectivity. This wire must be fused appropriately (see each amplifier’s fuse rating
under specifications) within 12 to 16 inches for safety. You will then need to connect the power wire to the 12+
terminal of the amplifier with a Phillips screwdriver. Do not install the fuses until installation is complete.
Ground Connection
It is recommended that you connect your ground directly to your power source ground for the best possible
performance. However, if you cannot, then the ground connection must be made to the vehicle’s chassis and
should be kept as short as possible, while accessing a solid piece of sheet metal in the vehicle. The surface
should be sanded at the contact point to clean rust, paint or grime so a metal-to-metal connection between the
chassis and the termination of the ground wire is effective. You will then need to connect the ground wire to the
GND terminal of the amplifier with a Phillips screwdriver.
Remote
The +12V remote turn-on wire is typically controlled by the source unit’s remote turn-on output. The amplifier will
turn on when +12V is present at its remote(REM) input and turn off when +12V is switched off. Connect the
remote wire using 12 to 16-gauge wire to the REM connection of the amplifier with Phillips screwdriver, then
connect the other end of the remote wire to either the source unit’s turn on output or ignition switch circuit. The
models that have the extra power input will have an extra REM connection noted as OUT, this is intended to
allow you to connect your REM line to other devices if needed.

Subwoofer planning
When using more than one subwoofer, you have to make sure your total impedance does not go below the
minimum level of the amp, see the specification charts for your amplifier’s minimums. Use the chart below to
help with your design.

only covers the original owner of the amplifier and is non-transferable. Wear and tear are not
considered a manufacturer defect.
All warranty returns must be accompanied by a copy of the original sales invoice or receipt. You must
contact us to request an RMA number prior to sending any returns via the RMA request form on our
website. You are responsible for the cost of shipping your amplifier back to us for warranty
consideration. If your amplifier is covered under warranty ground shipping back to you willbe no charge

TROUBLESHOOTING
All Sundown Audio amplifiers have multi-layer protection features to prevent damage from
misuse or faulty conditions to ensure long lasting life of your investment. If the unit senses
excessive heat, short circuited speakers, overload, or voltage fluctuation outside of the
working range the protection indicator light will turn red and the unit will turn off. In order to
solve this problem, you should turn all levels down, power off the unit, then carefully check the
installation for wiring mistakes or shorts. If the amplifier is excessively warm the protection
light will not turn on as the unit will turn off to protect itself from overheating. Let the unit cool
down for 30 minutes and try again. If the unit works, try moving the amplifier or make sure
nothing is covering it so it can vent heat from the heatsink. Before you remove or uninstall the
amplifier, refer to the list below for suggested solutions.
Amplifier Doesn’t Turn On or No Output
Check the fuse(s), not just visually, but with a continuity meter and all 12+ volt, remote and
ground connection. Make sure you have 13+ volts. It is possible for a fuse to have poor
internal connections, take the fuse out of the holder for the testing.
Check the input signal from the source unit using an AC voltmeter to measure the voltage
while it’s being played. The voltage should be from 0.2 to 6.0 volts from the RCA cables.
Check the output of the amplifier, test for output at the speaker outputs of the amplifier.
Check to ensure that the speaker wires are making a good connection to the amplifier and the
subwoofers.
Amplifier Goes Into Protection
Check shorts on speaker wires or open coil.
Check input voltage from RCA, if DC signal is over 4 volts, the amplifier will go into protect.
Remove and reset the power to the unit to check if it will turn on.
Check impedance to make sure it’s over the minimum load, see the specification charts in this
manual for the minimums of your specific amp.
Check input voltage. The amplifiers covered in this manual have a working range of 10.5 to
15.5 volts.
Check chassis ground and remote using same ground.
Distorted / Attenuated / Noise Sound
Check the chassis ground connections of all audio equipment.
Check amplifier controls for errors, input level or crossover setting.
Check the speaker wires for a possible short, either between the positive and negative leads
or between a speaker lead and the vehicle’s chassis ground.
Check the nominal load impedance to verify that the amplifier is driving a load equal to or
greater than the specified minimums, see the specification charts in this manual for the
minimums of your specific amp.
Check the input signal and input signal cables to make sure signal is present at the amplifier
inputs and the cables are not pinched or loose. It may be helpful to try a different set of cables
and / or a different signal source to be sure.
Check speaker wiring for reverse polarity.
If you hear a pulsing sound from your speakers, it means that there is something being overdriven.
This could be due to a gain being set too high or a speaker impedance being too low, see the
specification charts in this manual for the minimums of your specific amp.
