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.

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.

Connecting other Amps

RCA Output

The “output”signal allows you to conveniently

connect other amplifiers to each other.

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.
