+12VDC Power Connection
For optimum performance, connect an 8 gauge or larger 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 30 amp inline fuse. For safety
purposes, the fuse must be located within 16 inches (40cm) of the battery.
Channel 1 & 2 Speaker Outputs
Connect speaker wire up to 10 gauge. Channel 1 and 2 connections can be
configured in stereo using the + and – of both channel outputs, or in a bridged
configuration using CH1 + and CH2 -.
High Power/High Current Mode Indicator
This amplifier has a High Power and High Current power mode. Two LEDs are used
to indicate what mode the amplifier is in (refer to #12 for Mode Selection). When
High Power mode (default) is selected, the LED marked H/P will illuminate BLUE.
When High Current mode is selected, the LED marked H/C will illuminate YELLOW.
RCA Inputs
Accepts both low-level and high-level signal via RCA style connectors. Use the Input
Voltage Selector (refer to #9) to choose appropriate voltage level.
High/Low Level Input Voltage Selector
Select signal input voltage based on the signal source used. When using an
aftermarket 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 8V. 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.
Turn-on Mode Selector
Select between 3 modes to turn on the amplifier. When using a switched lead such
as the +12v remote output of a radio, use 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.
