Hifonics BRX316.4 Instruction Manual

Place terminal in a secure
position so that it won’t
accidentally contact the
negative battery post
Power cable size
and fusing
It is critical to use the proper power
and ground cable. Select the size
listed here for your amplifier model.
Always use high quality copper
cable. Visit our website for multi amp
system cable recommendations.
Be sure to use the proper fuse size
for each model. Some models require
an external fuse.
Properly route power,
speaker and RCA cables
through the vehicle.
Choose a mounting location
that will provide adequate air
ventilation. Mount the amplifier to
a secure surface. Do not mount
the amplifier upside down.
Attach the chassis ground
cable to the amplifier
negative terminal. It is
important to make sure this
connection is very tight.
Bare metal
Attach the main power cable
to the amplifier +12V. The
cable must run directly to
the battery and be properly
fused and be very tight.
Attach the remote turn on
wire to the amplifier remote
output of the source unit.
Connect the RCA cables to
the INPUT connectors. The
OUTPUT can be used to
provide input for a second
amplifier.
Connect the power cable to the
positive battery terminal. The
power cable must be fused
within 18 inches of the battery
terminal.
Re-connect the negative
battery terminal making sure it
is securely tightened.
Connect the speaker cables to
the speaker output connectors.
Follow the diagram below
that best fits your speaker
configuration.
The chassis ground connection
is critical to the performance
of the amplifier. Choose a
location that is close to the
amplifier. Completely scrape
away the paint and use a nut
and bolt if possible.
DO NOT USE AN EXISTING
FACTORY BOLT!

CAUTION
Many new and factory radios require a reset code when
disconnected from battery power. This is an anti-theft
feature. Before unplugging power, you must determine if
your radio/source unit requires a reset code. Check the
operation manual for your vehicle or contact the dealer.

Quick Start
Installation Guide
The input MODE switch will “sum” or
combine the right and left channel signals
in the MONO position to improve bass
performance. Select MONO only when the
amp is being used for subwoofers.
The XOVER Mode switch sets the type
of crossover that will be active. 4 channel
models will have two switches, one for each
set of channels.
The HPF(high pass filter) control will limit the
output below the selected frequency. This
is typically used to protect midrange and hi
frequency speakers from damage and to
allow a smooth transition from a subwoofer.
The LPF(low pass filter) control will limit
output above the selected frequency. This
is used to allow a smooth transition to the
higher frequency speakers.
1. If possible, with the source unit off, confirm that the primary volume control is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center or “0” adjustment. Make sure that the green LED on
the end of the amplifier is illuminated.
3. Play a clean musical selection of which you are very familiar. CD is preferred.
Do not use radio signals for level setting. Hit play and start turning the volume
of the source unit up.
4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until
you hear speakers begin to slightly start producing distortion.
5. Increase the amplifier level (clockwise) until distortion is heard, then back
the level down (counter clockwise) until the distortion is eliminated. Small
adjustments may need to be made to balance the levels of multiple amplifiers.
The Bass EQ control will increase the power
output at 45Hz for more pronounced bass.
Exercise caution when using this control.
Increase the level in small amounts until
distortion is noticed, then back off a little.
Some models include a bass
remote. Avoid adjusting the bass
remote while operating vehicle.

This is a critical step to insure your amplifier
is properly adjusted to match the signal
