17. INPUT LEVEL(PK700.4M/PK1400.4M only)
The amplifier has dual input sensitivity differential inputs which will receive either High level
(Speaker output) or Low level (RCA) signals from your car stereo's source unit.
When switch to PRE IN, The signal can be delivered to the amplifier using the low level RCA
outputs on the source unit.
When switch to SPK IN, The high-level signal can be run from the source unit’s speaker
outputs to the stereo RCA input on the end panel of the amplifier using the HL01.
18. Auto Turn On(PK700.4M/PK1400.4M only)
For auto turn on/off mode, PK1400.4M amplifier offer three options: DC Offset/Rem/Audio.
REM: When auto turn on to REM, please connect the unit REM terminal to the source unit
remote terminal with an 18AWG cable. This is the preferred mode.
DC Offset: If the OEM source unit has no REM signal output, You can choose DC Offset
(Meanwhile,Input select switch to SPK IN mode),DC Offset can turn on/off PK series
amp by detecting the 6V DC Offset from the OEM source unit terminal.
AUDIO: Audio mode can turn ON/OFF PK700.4M and PK1400.4M amp by detecting the audio
signal from source unit. Note: If the volume is too Low, The amp may fail to turn on. So please check
if the source unit volume is properly set.
19. RUN
This LED will light up when amplifier works properly.
20. ALARM
The red LED will light up and will be flashing if there is a fault presented to the amplifier. Please
disconnect the amplifier and resolve the fault before reconnecting the amplifier.
21. Limit Indicator
This LED will light up when output clipped or amplifier get over heat. When limit
indicator light up, the amplifier will hold or reduce output power to protect subwoofer and amplifier.
Please turn down volume or cool down the amplifier when this indicator
light up continually.
22. REMOTE
Connect the remote controller to control the Subwoofer amplifier volume from the driver seat
location, for ease of adjustment during playing.
23. RCA input jacks
These RCA input jacks are for use with source units that have RCA outputs. A source unit with
a minimum level of 200mV is required for proper operation. The use of high quality twisted pair
cables is recommended to decrease the possibility of radiated noise entering the system.
24. Bridge In
This RCA jack receives signal from the master amplifier when this amplifier is bridged as
slave. DO NOT use input jacks when the amplifier is working as slave. All the functions will be
adjusted by the master amplifier.
25. Bridge Out
This RCA output send out bridge signal to another same X-series amplifier in bridging
configuration. All the functions will be adjusted by the master amplifier.

Connect the amplifiers ground cable to a close, bare metal part of the frame or chassis. Use a
nut and bolt, Not a screw! The ground cable must be at least the same size as the +12Volt
cable.
Connect the remote terminal to remote output of the head unit using 16 gauge (or heavier)
wire.
Connect the fuse holder within 18”(45cm) of the car battery, and run the selected cable from
this fuse to the amplifier.
Connect all the inputs with high-quality cables. Connect Remote Control if necessary.
Insert fuse(s) into the battery fuse holder(s).
If using a subwoofer for 2-CH and 4-CH, bridge the channels by using the Left “+” and the
Right “-“ terminals.
