+12VDC Power Connection
For optimum performance, connect a 4 gauge OFC (oxygen-free copper) wire to the
+12V terminal. This wire should be connected directly to the positive terminal (+12V)
of the car’s battery in conjunction with a 100 amp inline fuse. For safety purposes, the
fuse must be located within 16 inches (40cm) of the battery.
Subwoofer Outputs
There are two speaker terminals l and two terminals labeled -. This is a single
channel amplifier so both pairs of the terminals are internally parallel. See Speaker
Connections.
RCA Inputs
Accepts both low-level and high-level signal via RCA style connectors. Use Input
Voltage Selector to choose appropriate voltage level. High-level inputs require the
MPS-LC line level adaptor (sold separately) to convert amplified speaker outputs from
factory audio systems to RCA style connections.
RCA Outputs
These are non-buffered through-pass outputs used to connect additional amplifiers.
Not that the internal crossover does not affect signal to these outputs.
High/Low Level Input Voltage Selector
Select signal input voltage based on the type of input used. When using an aftermar
-
ket radio, DSP or line level convertor, select Low for levels up to 4V. When using
high-level input from an amplified factory audio system, select High for levels up to
20V.
Remote Level Control
Connection 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.
Turn On Mode Selector
Select between 3 modes to turn on the amplifier. When using a switched lead such as
the remove output of a radio, select the default position REM. When connecting to a
factory audio system or alternative source, select Signal and the amplifier will turn on
when it senses voltage through the inputs. DC (DC offset) may be used in some
vehicles where signal sensing does not reliably turn the amplifier on.
