4. Control & Connection
4-1. Monoblock control
RCA JACK INPUT
Low Level Rca Input will accept the signal from the output of
head units. Plug in Rca jack cables from the head unit.
RCA JACK OUTPUT
The preamp output is a full range signal mixed from both input
channels. Use this signal to feed a secondary full range
amplifier in the system.
GAIN CONTROL ( 6V - 0.2V )
The gain control adjusts the gain level. so that this is used to
match the signal level of different headunits.
LOW PASS FILTER ( 35Hz - 250Hz )
Linkwitz-Riley low pass crossover ensuring that only
the lowest frequencies are reproduced by the amplifier.
SUBSONIC FILTER ( 10Hz - 50Hz )
Control the high Pass point for the speaker outputs
to eliminate extreme low frequencies.
REMOTE CONTROL PORT
This port is for connecting the remote gain control.
Remote control can be mounted around driver’s seat for easy access.
POWER, PROTECT & CLIP INDICATOR
POWER LED : Green-lit shows correct operation.
PROTECT LED : Red-lit shows general malfunction, faulty connection
or thermal protection.
CLIP LED : When input signal is close to clipping level, CLIP LED begins to
light up.
At full clip, the protection LED will light up
3-2. Multi-Channels

RCA JACK INPUT
Low Level Rca Input will accept the signal from the output of
head units. Plug in Rca jack cables from the head unit.
GAIN CONTROL ( 6V ~ 0.2V )
The gain control adjusts the gain level. so that this is used to
match the signal level of different headunits.
HIGH PASS FILTER ( 50Hz ~ 500Hz )
Linkwitz-Riley high pass crossover ensuring that only
the highest frequencies are reproduced by the amplifier
LOW PASS FILTER ( 50Hz ~ 500Hz )
Linkwitz-Riley low pass crossover ensuring that only
the lowest frequencies are reproduced by the amplifier.

BATTERY
Fuse
GND ( GROUND )
Locate a secure grounding connection as close to amplifier as possible.
Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle.
The ground needs to have as low of a resistance as possible.
Connect one end of a short piece of the same size cable as the power cable to the grounding point or to one
of your baeries or baery bank.
Run the other end of 4 ( 0 ) gauge cable to the mounting location of the amplifiers for connection
to the amplifiers ground terminals and connect the ground cable to the GND ( ground terminal ).
Working Baery voltage
9V to 16volts
3

4-4. Monoblock speaker connection.
1100.1 & 2100.1
Minimum working impedance is 1ohm.
Impedance lower than 1ohm can damage the amplifier
Caution !!
4 ~ 1 ohms
REM ( REMOTE )
Run a remote turn on cable from the switched + 12V source . This may be a toggle switch, a relay,
your source unit's remote trigger cables, or power antenna trigger cable. Connect the remote turn on cable
to the REM ( remote ) terminal.
+12V ( POWER CONNECTION )
Before mounting amplifiers, disconnect the negative ( ) cable from the baery to protect any accidential damage
to your awesome amplifiers and audio system.
Amplifiers are designed to use 4 ( 0 ) gauge power and ground connection.
Connect the power cables to power terminal + 12V.
All amplifiers do not have built-in fuses so they need external fuse connection.
Connect one end of fuse holder to the power cable going into the amplifiers and the other end of fuse holder
to positive baery.
This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power cable.
Be sure to use fuses and fuse holder adequate for the application.
SPEAKER OUTPUT
This terminal connects the amplifiers to the speaker systems. Minimum speaker cable should be larger than
12 gauge.
Connect carefully the subwoofer or the speakers by checking the impedance 1ohm for 1100.1 & 2100.1
2ohm stereo or 4ohm bridged for 300.4 & 1000.4
4

4-5. 4 channels speaker connection.
300.4 & 1000.4
Minimum working impedance is 2ohm stereo or 4ohm bridged.
Impedance lower than 2ohm can damage the amplifier
Caution !!
8 - 4 ohms

5. TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
@ Please check all connections, cables' rounting, short & voltage
@ Please check the fuses , If they are blown, please replace with new one.
@ Please check whether speakers work well, you can test speakers by connecting to another amplifier
PROTECTION
@ Please check overload, overheat ( thermal ), short and voltage, DC offset.
@ Minimum working impedance is 1 ohm for 1100.1 & 2100.1.
2ohm stereo or 4ohm bridged for 300.4 & 1000.4.
@ If amplifiers are shut down due to heat, they will be on some minutes later aer cooling down.
Please make beer airflow and no obstruction around amplifiers for thermal protection.
@ All amplifiers working voltage is 9V ~ 16Volts.
@ When over 4V DC comes into amplifiers, then, they will be DC protected.
Check whether amplifiers work aer removing RCA-Input.
If amplifiers work, then check DC by checking RCA-input .
When DC is over 4V at input, try by replacing +12V source unit .
DISTORTION & NOISE
@ Readjust input level and check the speaker quality at another amplifier.
Replace poor quality speakers with good quality ones.
@ Check amplifiers and headunit’s ground contact. all grounds should be common.
@ Check Rca Jack, then repalce with new one or reroute Rca Jack.
@ Engine noise is caused by poor grounding of amplifiers, headunit, other components, baery or
alternator, so please check all grounding connection.
POOR BASS RESPONSE
@ Please check speaker cables and reverse polarity.
