RoutingWires
Location and Mounting
The A400HLX/A600HLX amplifier’s compact
design allows greater flexibility in mounting. It
can be mounted under a seat or in the trunk.
When selecting a location, remember that
amplifiers generate heat. Select a location
where air can circulate around the amplifier.
Do not cover the amplifier with carpets or
enclose it behind interior trim panels. Do not
mount the amplifier in an inverted or upside
down configuration. Every installation will be
a bit different based upon vehicle design.
Check all locations and placements carefully
before making any cuts or connections.
Important
Allow air circulation around the amplifier.
Important
If wiring connections are made wrong, the unit
will not operate properly and it could be
damaged. Follow the installation instructions
carefully, or have the installation handled by
an experienced technician.

RemoteTerminal (REM)PowerTerminal (+12V)
Connect directly to the vehicle battery+
terminal with 8 gauge wire (minimum).
GroundTerminal (GND)
Connect to a good chassis ground. The ground
connection should be to clean, unpainted metal
to provide a good electrical connection.
Connect the power antenna/amplifier turn-on
lead from the receiver to the AMPLIFIER
REMOTE terminal.
Use only blade-type fuses.

Inputs, RCA Output, Remote Level Control
InputWiring
Low Level Input (RCA Input)
Low level (RCA) input is preferred for best
performance. Most trunk/hatchback installations
will require a 15-20 foot RCA cable. While pick-
up trucks and under-seat mounting will require
a 6-12 foot RCA cable.
Connect an RCA cable
from your receiver to the RCA input on your
amplifier.
High Level Input
High level input should be used when an RCA
output is not available from the receiver.
Connect the speaker outputs from the receiver
to the high level input connector.
Important
Only connect the low (RCA) or high level input.
Do not use both at the same time.

Remote Level Control –Rear
Amplifier (A600HLX)
Remote level control allows
the input level to be adjusted
for the rear speakers from an
alternate location. It can be
mounted under-dash or in-
dash.
When the amplifier is used to
drive subwoofers, and the low
pass crossover is activated,
the remote level control can be
used as a “remote bass level
control”. This enables you to control the
bass level, independent from the rest of the
system. This is convenient for system
tuning and/or when playing many different
types of music.

The “output”signal allows you to conveniently

Tri-mode (A400HLX)
Important
When running a subwoofer and two
full-range speakers together (Tri-
mode operation), high and low pass
filters must be used. Failure to install
these filters may damage your amp
and/or speakers.

Adjust the crossover to accommodate your
chosen installation method.
•LPF–(low pass filter) Select
this filter when the amplifier will
be driving woofers or
subwoofers.
•FULL–Crossover is not active,
amplifier is in “full range”
mode.
•HPF–(high pass filter) Select
this filter when the amplifier will
be driving full range/separate
speakers, and you want to limit
the “bass”going to these
speakers.
Crossover (X-OVER)
Indicators and Controls
A dual status LED indicator illuminates
red or green to indicate the status of
the amplifier.
Power / Protect Light
Green –Power applied, ON
Red –Protection circuit activated, STANDBY
Tri-mode/Three channel operation
An amplifier is usually configured for tri-mode
operation when you want to use one amplifier to
drive a pair of front speakers and subwoofer(s).
In other words, when you want drive a complete
system with one amp. Your Jensen amplifier is
capable of tri-mode operation.
Important
Tri-mode operation requires using “passive
crossovers”.These crossovers are available at
your local retailer or install shop. Failure to
install these filters may damage your amplifier
and/or your speakers.
