TERMINALS AND CONNECTIONS
3. Speaker Output Terminal
For connection to the speakers. See page 8 and 9 for wiring examples.
4. Low Level Input
For connection to any source (head unit) with a low level output. This is your RCA output from the
source (headunit)
5. Low Level Output
Used to connect additional amplifiers with RCA input.
6. Power / Protect LED
When the amplifier is operating correctly the green LED will illuminate.
When the amplifier is in protection mode the red LED will illuminate.
7. Gain Control
Used to match the input signal of the source to the amplifier. See the setup section for more details.
8. Subsonic Filter Control
This control allows the subsonic filter frequency to be set, the filter is adjustable from 10Hz to 70 Hz.
9. Bass Boost level Control
This control provides up to an extra +9 dB of bass boost at the chosen frequency. Use this boost to
increase bass output from the amplifier.
10. Bass Boost Frequency Control
This control sets the frequency that will be boosted by the bass boost control, the frequency ranges
from 30Hz to 90Hz.
11. Low Pass Crossover Control
This control is used to set the crossover point for the amplifier.
The frequency ranges on the low pass filter are from 35 Hz to 250 Hz.
12. Phase Control
This allows the phase of the amplifier to be adjusted from 0 to 180 degrees.
2. Power Input 1
Only 0 gauge cable should be used for the power and ground connection to the amplifier.
The power cable should connect directly to the batteries with a 900 amp fuse inline no
further than 18 inches in wire length from the battery and this fuse must be fitted before
the power cable enters a bulkhead.
Please ensure that the fuse is not fitted until installation is complete and all wiring is checked.
Rubber grommets must be used when passing the power cable through a bulkhead to
prevent the cable becoming chaffed or cut.
The ground cable should be connected directly to the chassis ground of the vehicle and ideally
to bare metal.
The ground cable length should be kept to an absolute minimum.
It is not recommended that you connect the ground cable to the vehicles seat belt ancor points.
A minimum of 18 gauge cable should be used for the remote turn on connection.
The cable should be run with the same care and attention as the power cable and use grommets
if necessary.
