The above chart shows cable gauges to be used, if no less than a 0.5 volt drop is acceptable. If aluminum wire or tinned wire i s used, the gauges
sould be of an even larger size to compensate. Cable gauge size calculation takes into account terminal connection resistance. 1 Metre = 3.28 Feet

2 Subwoofer Installation
Class-D MONO Block Amplifier
SC 1.500
Operational Details
Set up Stacking
(1)RCA INPUT : Connect these RCA connectors to a head unit with a LOW LEVEL output connection.
RCA OUTPUT: Use these RCA output connectors to connect to a secondary amplifier.
(2)SPEAKER OUTPUT
See installation diagram in this manual for correct speaker connection. PLEASE NOTE : The two (-) terminals are
internally wired in parallel inside the amplifier as well as the two (+) terminals
(3)FUSES : Please ensure correct type of fuse is fitted.
(4)+12V INPUT
This must be connected to the vehicle battery positive(+) terminal via correct power cable and with an inline fuse or circuit breaker
at the battery end. NOTE : This is to be the last wire connect up during installation as damage could result.
(5)REMOTE INPUT
This terminal is for turning the amplifier on and off. This requires a switched postive (+)12V to power 'ON' the amplifier, this can be
found on the rear of the head unit in the form of a electric antenna output, or a remote on output. If not available you can wire to the
ACC position on the key.
(6)GROUND INPUT
Connect directly to the vehicle's chassis via correct ground cable. NOTE : This is to be the first wire to connect when wiring up an
amplifier. Damage could result if this is not done.
(7)CROSSOVER SELECTOR
Set the appropriate mode. The 2 positions available are flat and LP
(8)LOW PASS
Set the crossover switch to LP when a subwoofer is connected. Ensure the crossover frequency is set at 100Hz or below.
NOTE : Failure to do so could result in speaker damage.
(9)BASS BOOST
This is a variable control to increase the bass boost at 45Hz from 0 - +12dB of gain, adjust to suit.
(10)GAIN (LEVEL)
This allows level adjustment of the input signal. Use this control to correctly match 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 this amplifier
level control towards the MAX end of the control. NOTE : If the sound becomes distorted, turn this control down.
(11)SUBSONIC FILTER
This is a selectable and will filters out 20Hz and below at 9dB/octave.
(12)POWER, STATUS AND THERMAL LED's
This shows if the amplifier has been correctly powered up and if any faults are present.
