Positive Power Terminal - This is the power feed from the
positive (+) terminal of the car’s battery. Use 8 gauge cable
and good quality terminals when routing this connection.
Tighten the connections well to prevent power loss due bad
contact. Route the power cable away from the RCA and
speaker cables
HOOKUP INTO TWO 4 OHM WOOFERS

OUTPUTS
Fuses - Replace these fuses with only with the same type
and value. These fuses only protect the amplifier. An
additional inline fuse should be added at the battery to
protect against a short in the main power cable to the
amplifier.

Ground Terminal - For optimum performance, an 8 gauge
cable and good quality connectors should attach the this
terminal to the battery’s negative (-) terminal.
+
Remote Terminal - The amplifier will turn on when 12 volts
is applied to this terminal. This 12 volt signal is usually taken
from the Power Antenna or Remote wire coming from the
source unit.

Speaker Terminals - Connect to speakers using at least 14
gauge speaker wire. Note that there are two Sp+ and SP-
terminals that are internally wired in parallel to the + and -
output of the class D stage. These are provided for easier
connection of multiple speakers and should not be confused
with the traditional Left and Right stereo hookup of traditional
amplifiers. Running too low of a speaker impedance will
cause the amplifier to go into a fault condition.

45Hz Bass Boost – This control will add up to 12db of boost
at 45Hz to give the music more ‘kick’. Be careful! This added
boost could run your speakers into clipping when listening to
bass intensive music.

High level inputs
Lowpass Filter – Butterworth 12db slope. This control sets
the 3db down point of your amplifier. Higher frequencies
beyond this setting are not heard from your speakers.

Gain – 20db of signal gain is available. This allows input
levels between 150mV and 2 volts for full output.
Inputs – Two RCA jacks are provided. Their signals are
added together inside the amplifier and the bass information
is extracted. Since they are summed together, it does not
matter which one is ‘Left’ or ‘Right’.

High level inputs – These are provided for use with head
units that do not have RCA outputs. Attach the appropriate
speaker outputs from the head unit to the terminals provided.
