A. POWER STATUS LED
The LED indicator light glows GREEN when power is ON and
no problems are present. If one of the protection circuits
comes on, the light will change to RED
B. PHASE SHIFT
Use this switch to compensate for time alignment
issues. These issues are usually the result from having
the subwoofer at a different distance from the listener
than the other speakers in the system.
C. AUTO POWER ON
NOTE: If you experience a POP noise from the subwoofer
when powering ON/OFF, confirm you have it wired to the
remote output of the head unit as shown in FIGURED 4.
NOTE: The low pass filter frequency can be higher or lower
than the standard. There is a +/- 20% tolerance.
The AUTO POWER ON (ON/OFF) is for high level
(speaker-level) connections. When the switch is in the ON
position, the subwoofer will AUTO POWER ON when there is
signal input present. If the amplifier does not detect a
signal, the amplifier will auto turn OFF. If you prefer to
use the remote turn on/off connection, switch can be
changed to OFF.
D. LOW PASS FILTER
This control allows for the adjustment of the frequency
range you want the subwoofer amplifier to receive. The
subwoofer will reproduce all sounds BELOW the frequency
you set on the LPF.
E. BASS BOOST
The BASS BOOST feature will increase the sound level in
the bass frequencies.
F. INPUT GAIN CONTROL
After you’ve installed your system, turn this control to a
minimum.
Turn the head unit ON (the subwoofer will turn on via the
remote connection). Turn the head unit volume to 2/3 full
level.
Slowly turn up the subwoofer input gain control until you
hear a small amount of distortion. Begin reducing the
level until the distortion is completely gone. Level the
control at this setting.
G. REMOTE LEVEL CONTROL
Attach the included remote level control to control the
volume level of the subwoofer independently.
H. HIGH LEVEL (SPEAKER LOW) INPUTS
If your head unit does not have RCA outputs, you can use
the speaker outputs for the audio source for the
subwoofer. Use the supplied cable and wire harness to
connect the outputs properly as shown in the connection
diagram in this manual.
I. LOW LEVEL RCA INPUTS
Low level inputs are the recommended way to introduce
the audio signal to the subwoofer. If RCA outputs are
present on your head unit or other signal source
(processor etc) this is the preferred way to connect your
NANOBOXX
J. FUSE
DO NOT USE A FUSE WITH A DIFFERENT VALUE. and NEVER
replace the fuse with a wire, coin or anything other than
the recommended fuse rated for this device.
Be certain all power connections are mounted securely
and use the correct gauge wire for the NANOBOXX.
K. POWER INPUT TERMINAL

NOTE: Do NOT connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time!
TO AUDIO OUTPUTS OF HEAD UNIT OR SIGNAL PROCESSOR
TO SPEAKER TERMINALS OF HEAD UNIT
LOW LEVEL INPUT WIRING
Low-level RCA input wiring is preferred for the best audio performance. Always use a high quality RCA cable to carry the signal
to your NANOBOXX for the best quality performance. Memphis Connection wires are the preferred choice to feed your system
the high performance signal you need.
NOTE: Do NOT connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time!
HIGH LEVEL INPUT WIRING
The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect
the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid
audio phase issues.

Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to less than 39” in
length. Use 8 gauge or heavier wire.
Connect the remote terminal to the remote output of the head unit using 16 Gauge or heavier wire.
Connect an empty fuse holder within 18” of the car battery. Run 8 gauge or heavier cable from this fuse to the amplifier
location. Connect the fuse holder to the BAT+ (+12V) connection on the subwoofer rear panel. .
NOTE: In this connection, the AUTO
TURN OFF switch is in the ON position.
NOTE: In this connection, the AUTO
TURN OFF switch is in the OFF position.

REMOTE LEVEL CONTROL

TROUBLE SHOOTING
AMPLIFIER DOES NOT POWER ON Check ground is connected properly
Check the Remote input (turn on) has at leas 5V DC.
Check that there is battery power on the + terminal
Check that there is at least 12V
Check all fuses, replace as needed
Be sure the Protection LED is not illuminated. If it is lit, shut off the amplifier briefly
and then re-power it.
PROTECTION LED COMES ON WHEN
AMPLIFIER IS POWERED ON
Check for short circuits on speaker leads
Turn down the volume control on the head unit to prevent overdriving remote
speaker leads and reset the amplifier. If the protection LED still turns on, the
amplifier is faulty and needs service.
NO OUTPUT
LOW OUTPUT
Check all fuses are okay. Replace if necessary.
Check unit is properly grounded
Check the remote input (turn on) has at least 5V DC
Check the RCA audio cables are plugged into the proper inputs
Check all speaker wiring.
Reset the level control
Check the crossover control settings.
HIGH HISSING SOUND
Disconnect all RCA inputs to the NANOBOXX. If the hiss disappears, then plug the
components in one by one to establish which component is causing the hissing noise.
It is best to set the amplifiers input level control as low as possible. Try to set the
head unit as high as possible (without distortion) and the amplifier input level as low
as possible.
SQUEALING NOISE IS PRESENT
Check for improperly grounded RCAs
DISTORTED SOUND
Check that the input level control is set to match the signal level of the head unit.
Always try to set the input level as low as possible.
Check that all crossover frequencies are properly set
Check for short circuits on the speaker lead.
AMPLIFIER GETS HOT
Check that the minimum speaker impedance for the amp model is correct.
Check that there is good circulation around the amplifier. If proper circulation is
not present you may need to add an axillary fan to help cool the device.
ENGINE NOISE (STATIC TYPE)
This is usually caused by a poor quality RCA cable which can pick up radiated noise.
We recommend Memphis Connection RCA cables.
ENGINE NOISE
(ALTERNATOR WHINE)
Check that the RCA grounds are not shorted to the vehicle chassis.
Check that the head unit is properly grounded.
If you experience operation or performance problems with this product, first double check you have it wired according
to the diagrams in this manual. If problems persist, see troubleshooting guide below.
