Installation
Before You Begin
Before you begin, you will need tools, supplies
and adapters. It is best to make sure you have
everything you need before you start.
• Traditional input circuitry – low and high level
inputs
• Pre-amp output for installation flexibility
• Dual status LED diagnostic indicator
• Thermal, short circuit and low impedance
protection circuitry
• PWM MOSFET power supply
• Discrete amplifier design with complementary
high current Bi-polar output stage
Supplies and Tools Needed
Supplies
• Black electrical tape
• Amplifier Installation Kit
Disconnect Battery
Before you begin, always
disconnect the battery
negative terminal.

Tools
• Cordless drill with assortment of bits
• Flat and Phillips screwdrivers
+
–
• Wire cutters/strippers
• Crimping tool
• 12-volt test light or digital multimeter
• Wire brush, sandpaper or scraping tool
(ground connection to vehicle should be a
clean, unpainted metal surface)

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.
