1. Power Status Indicator
LED illuminates blue when amplifier is properly powered on
2. Protection Status Indicator
LED will illuminate red when the amplifier is in faults into protect mode related to over
current, short circuit, thermal protection or internal error within the amplifier. If the fault
is caused by thermal protection, the amplifier will reset automatically once the heatsink
has cooled to about 70°C (160°F). If the protection LED stays illuminated, turn the
amplifier off and check the speakers and wiring.
3. Negative Chassis Ground Connector
Connect to a matching 8 gauge or larger OFC (oxygen-free copper) wire for ground
as used the power wire. The length of the ground wire should not exceed 36 inches
(90cm) from the amplifier. To ensure a solid connection, remove surface paint at the
ground point prior to securing the connector in place.
4. Remote Turn-On Connector
Connect to wire lead from a sw12V source. This could be from a head unit or
switched ignition lead. If neither of these sources is available, switch Turn On Mode to
signal sensing or DC offset.
5. +12VDC Power Connection
For safety and optimum performance, connect an 8 gauge or larger OFC (oxygen-free
copper) wire to the +12V terminal. Connect directly to the positive terminal (+12V) of
the car’s battery via a 50A inline fuse. The fuse must be located within 16 inches (40cm)
of the battery.
6. Subwoofer Outputs
There are two speaker connections are l and -. The two output connections
are internally parallel as this is a single channel amplifier. When using both sets of + and
-, you will need to use Ohm’s law to calculate the impedance in a parallel configuration.
Connect speaker wire up to 10 gauge.
7. Remote Level Control
Connector for optional MPS-R1 remote subwoofer level control. This allows
the user to adjust the output level of the amplifier on the fly from a remote location
within the vehicle.
