To ensure best possible performance from the
amplifier a switch is installed to select between
High and Low input.

When using High Level input:

Push in the button to position
”High Level”

When using Low level input:

Push out the button to position
”Low Level”

To ensure best possible performance from the
amplifier when used with high level input a switch
is installed to select between Automatic amplifier
start and remote wire start.

When using High Level input with
automatic start:

Push the button to position 

IN

When using High level input with
remote wire start:

Push out the button to position 

OUT

NOTE!

Some head units use BTL output IC:s that have a
constant 6-12 Volt + on the speaker terminal, also
when shut off (the Power LED indicator lights
constantly even when the head unit is off). In this
case you have to use a separate remote wire
connected to the REMOTE-terminal instead.

Input and controls

Input Wiring

Inputs may be low level from the RCA output of the
car stereo, or high level from the car stereo speaker
output. Low level = RCA is to prefer for the best sound
quality.

High / Low level input switch

Low level input

Use a pair of shielded stereo audio cables with RCA
type jack. Most trunk-mount amplifiers need a 20
feet RCA cable ( appr 5 – 6 meters). Most under
the seat installations require 12 feet ( 2 – 3 meters)
RCA cables. Avoid placing the RCA cable close to
speaker cables, power cables and remote control
cable. Connect to RCA input
sockets. Both inputs must be
connected. Use a Y -split if
necessary.
Set the input selector switch
to position ”

”.

High Level Input

Connect left and right speaker wires coming from
the car stereo to the high level input as shown. You
must connect both plus and minus as the inputs
are balanced, connecting plus only gives lower level
and bad sound quality. By changing the polarity of
plus and minus, you can change the phase.

With the ”

Input selector switch

” set to 

High level

and the ”

High level Auto Start

” switch set to 

IN

,

the amplifier turns on automatically on high input.
You don´t need to connect a separate remote wire
from your head unit.
If you want to use high level
input but use a remote start  wire, just set the ”

High

” switch to 

OUT.
