Set Output master / input slave switch to input slave position for Slave amplifier
Connect RCA cable from RCA OUT at master amplifier to RCA IN at slave amplifier.
MASTER / SLAVE ( STRAPPABLE )
12V ( POWER CONNECTION )
Before mounting amplifiers, disconnect the negative ( - ) cable from your grounded battery to protect any
accidential damage to your awesome amplifiers and audio system.
BC amplifiers are designed to use 0 gauge power and ground connection.
Connect the power cables to power terminal + 12V.
BC amplifiers are not equipped with fuses because they do not like to be bossed around.
External fuses should be used.
Connect one end of fuse holder to the power cable going into the amplifiers and the other end of fuse holder to
positive battery.
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.
REM ( REMOTE )
Run a remote turn on cable ( at least 18 gauge ) 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.
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 batteries or battery bank.
Run the other end of the 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 ).

SPEAKER OUTPUT
This terminal connects the Crescendo BC amplifiers to your speakers . Minimum speaker cable should be
12 gauge or larger since our amplifiers put out epic power.
Connect the speakers by checking the impedance as 1 ohm for single unit or 2 ohm for link connection.
LINK CONNECTION
INPUT CONNECTION ;
Step 1. Connect the master amplifier to the head-unit and set its output master / input slave
switch to output master.
Step 2. Set slave amplifier output master / input slave switch to slave input.
Step 3. Connect RCA cable from the master to slave amplifier as shown in the diagram.

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 all BC amplifiers as single unit.
and 2 ohm stable for linked operation.
@ If amplifiers are shut down due to heat, they will be on some minutes later after cooling
down.
Please make better airflow and no obstruction around amplifiers for thermal protection
@ BC2000D’s working voltage is 8.5V ~ 16V
BC3500D & BC5500D’s working voltage is 8.5V ~ 18V.
@ When over 4V DC comes into amplifiers, then, they will be DC protected.
Check whether amplifiers work after 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,
battery or alternator, so please check all grounding connection.
POOR BASS RESPONSE
@ Please check speaker cables and reverse polarity.
