LEVEL CONTROL  
This control is used to match the input level of the amplifier to the output level of you head unit. We recommend  
the following method. NOTE: Remove screws and the top cover of amplifier to access controls.  
1.  
2.  
Turn the amplifier level to zero  
3.  
Adjust the level control until the desired  
maximum volume is achieved without  
distortion.  
Turn the volume of the head unit to ¾ and the  
bass and treble to zero  
4.  
Failure to follow these steps may cause  
permanent damage to the audio system.

1. SPEAKER OUTPUT:  
Connect your subwoofer(s) to these terminals.  
9. GROUND CONNECTION:  
Connect directly to the vehicle’s chassis via a 4 guage power  
cable. NOTE: This is the first wire to connect up during the  
installation.  
NOTE: The positive (+) and negative (-) are internally linked.  
2. REMOTE LEVEL CONTROL CONNECTION:  
Connect the optional (supplied) Remote Level Controller to  
this socket.  
10. LEVEL CONTROL:  
This allows level adjustment of the input signal. Use this  
control to directly match the head unit to the amplifier. To  
set this control correctly, turn the amplifier level to MIN and  
the head unit to 3/4 volume, with the bass and treble on zero,  
then slowly turn up the level control towards the MAX end of  
the control. NOTE: If the sound becomes distorted, turn this  
control down.  
3. RCA INPUT:  
Connect these RCA connectors to a head unit with a low level  
output connection.  
4. RCA OUTPUT:  
Use these RCA connectors to connect to  
a
secondary  
amplifier. This output is a pass-thru connection derived  
from the RCA input connectors so that the signal level and  
frequency response is the same as the original input signal.  
11. SUBWOOFER LP FILTER FREQUENCY:  
This sets the crossover frequency point for the subwoofer  
channels’ low pass filter between 32Hz and 320Hz.  
5. POWER AND STATUS LED’S:  
12. FUSION LOW FREQUENCY CONTROL:  
This displays “green” if the amplifier has been correctly  
powered up & ‘red’ if any faults are present.  
The FUSION Low Frequency Control (F.L.F.C.) is a dual stage  
control interface. The combination of a Subsonic filter and a  
Bass Boost control allows precise shaping of the audio signal  
for your subwoofer(s). The Subsonic filter is essentially a  
high-pass crossover which blocks the frequency signal from  
10Hz - 80Hz. This signal often contains no music and its  
removal will improve subwoofer control. The Bass Boost is a  
variable control to increase the level at 45Hz from 0 - +12dB  
of gain. Adjust these controls with extreme care.  
6. FUSES:  
Please ensure the correct type of fuse is fitted. For CA-  
DA12250 3 x 40A fuses.  
7. +12V CONNECTION:  
Connect directly to the vehicle battery positive (+) terminal via  
a 4 gauge power cable, with an inline fuse or circuit breaker  
at the battery end. NOTE: This is the last wire to connect up  
during installation. Damage could result if this is not done.  
8. REMOTE TURN-ON CONNECTION:  
This terminal is for turning the amplifier on and off. The  
remote input requires a switched positive (+12V) to power  
‘ON’ the amplifier. This can usually be found on the rear of  
the head unit in the form of a remote output. If not available  
you can wire to the ACC position on the ignition key.

set this control correctly, turn the amplifier level to MIN and  
the head unit to 3/4 volume, with the bass and treble on zero,  
then slowly turn up the level control towards the MAX end of  
the control. NOTE: If the sound becomes distorted, turn this  
control down.  
3. REAR RCA INPUT:  
Connect these RCA connectors to a head unit with a rear low  
level output connection.  
4. FRONT RCA INPUT:  
Connect these RCA connectors to a head unit with a front low  
level output connection.  
13. REAR FILTER FREQUENCY:  
This sets the crossover frequency point for the rear filter  
between 32Hz and 320Hz. NOTE: Failure to correctly set  
could result in speaker damage.  
5. POWER AND STATUS LED’S:  
This displays “green” if the amplifier has been correctly  
powered up & ‘red’ if any faults are present.  
14. REAR FILTER SELECTION:  
6. FUSES:  
This switch selects the type of filter used for the rear audio  
signal. Either Low Pass, High Pass or Full Range can be  
selected. The Low Pass filter is designed to filter out all mid  
to high frequencies that only full range speakers should  
produce. The High Pass filter is designed to filter out all  
low frequencies that only subwoofers should produce. Full  
Range allows all frquencies.  
Please ensure the correct type of fuse is fitted.  
For CA-DA41400 2 x 40A fuses.  
7. +12V CONNECTION:  
Connect directly to the vehicle battery positive (+) terminal via  
a 4 gauge power cable, with an inline fuse or circuit breaker  
at the battery end. NOTE: This is the last wire to connect up  
during installation. Damage could result if this is not done.  
15. FRONT FILTER SELECTION:  
This switch selects the type of filter used for the rear audio  
signal. Either Low Pass, High Pass or Full Range can be  
selected. The Low Pass filter is designed to filter out all mid

produce. The High Pass filter is designed to filter out all  
low frequencies that only subwoofers should produce. Full

between 32Hz and 320Hz. NOTE: Failure to correctly set  
could result in speaker damage.  
10. REAR LEVEL:  
This allows level adjustment of the front input signal. Use this  
control to directly match the head unit to the amplifier. To  
set this control correctly, turn the amplifier level to MIN and  
the head unit to 3/4 volume, with the bass and treble on zero,  
then slowly turn up the level control towards the MAX end of
