Allow for air to circulate around the amplifier. Do not mount inverted or upside down. Do not cover with
carpeting or enclose it behind interior panels. Avoid mounting under a seat.
LocationLocation
When choosing a location for the amplifier, keep in mind that the amplifier will generate heat. Place the amplifier in
a location that allows air to circulate around it. Amplifier location and installation will vary from vehicle to vehicle,
depending on physical layout of the vehicle. Carefully consider as many installation locations and configurations
as is practically possible DO NOT COVER the amp with carpet or enclose it behind interior panels. DO NOT
mount inverted or upside down. The amplifier may be mounted vertically.
Before permanently installing your VRA2.0 Amplifier, place the VRA2.0 Amplifier in the approximate place it will
occupy in your car. Run all power and speaker wires inside the vehicle toward the amplifier prior to mounting. This
will allow you to estimate how much wire you'll need and where to route the wires inside your vehicle.

GAIN Control
The GAIN control matches the line output of your car stereo's RCA jacks to the line inputs of the
amplifier. When you have completed installing the amplifier, the gain control must be set at no
more than half way to prevent damage to the amplifier. Play a CD or cassette on the car stereo,
set the BASS and TREBLE at 50%, and set the equalizer, if you have one, to flat across all
frequencies. Also, set the left & right balance and front & rear fader settings are set in the middle.
If you have any distortion at these setting, then turn the gain down until the distortion disappears.
Frequency Adjustment Screw
The frequency adjustment screw (FREQ.) only has an effect if the crossover switch is set to
"BASS" or "TREBLE". When the crossover is set to FLAT it has no effect
To set the FREQ. when the crossover is set to BASS, turn FREQ. all the way to the right, this
allows a range of sound from 50 Hz - 250 Hz to the subwoofer(s). As you turn the FREQ. to the
left (counterclockwise), you will be cutting off the high frequencies coming from the
subwoofer(s).
To set the FREQ. when the crossover is set to TREBLE, turn FREQ. all the way to the left
(counterclockwise) this will allow the full range of sound to the front speakers. As you turn the

Bass Boost should not be turned on if you have Bass Control or Loudness on your stereo head
unit.
The line inputs on the front of the amplifier receive low level, high impedance signals from the low level RCA
outputs of the car stereo. The amplifier receives the signals and converts them to high level, low impedance
signals to be used to drive the speakers. All of the amplifiers line inputs need to be connected to the car stereo,
in order to use all of the speaker outputs.
The line inputs on the front of the amplifier receive low level, high impedance signals from the low level RCA
outputs of the car stereo. The amplifier receives the signals and converts them to high level, low impedance

in order to use all of the speaker outputs.
To use two full-range speakers with the
amplifier, connect one speaker to the
right channel and the other speaker to
the left channel as shown FIGURE 1. Set
the crossover switch to FLAT.
The FLAT setting allows the full range of
sound to the speakers. When the
crossover switch is set to FLAT, the
FREQ. adjustment screw has no effect.
To connect two single voice coil 4 ohm
subwoofers to the amplifier, connect one
subwoofer to the right channel and the
other subwoofer to the left channel as
shown in FIGURE 2. Set the crossover
switch to BASS.
To connect one dual voice coil 4 Ohm
subwoofer to the amplifier, connect one
voice coil to the right channel and the
other voice coil to the left channel as
shown in FIGURE 3. Set the crossover
switch to BASS.
To connect one 4 ohm subwoofer to the
amplifier by bridging the speaker
terminals on amplifier, connect the
subwoofer's positive (+) terminal to the
positive (+) terminal of the amplifier's left
channel, then connect the negative (-)
terminal of th e subwoofer to the
negative (-) terminal of the amplifier's
right channel as shown in FIGURE 4. Set
the crossover switch to BASS.
The pre-amp line outputs allow
unamplified signals to pass
through the amplifier to be used

system.

RCA "Y" Adaptors Not Included
Shielded RCA Cable
Not Included
For best sound performance use Shielded RCA Cables
to connect the Line Outputs from your stereo to ALL
FOUR (4) Amplifier Line Inputs. Shielded RCA Cables
prevent electrical interference from the vehicles
electrical system, and also radio frequency interference.
Your car stereo may only have 2 line outputs (left &
right), RCA "Y" Adaptors will be needed to split the left
and right signals into 2 right channels and 2 left
channels, one of each channel for both the front and
rear inputs. (See Fig.1)
If your stereo does not have RCA type output jacks, a
high level to low level adaptor will need to be
purchased. The high level to low level adaptor takes the
signals from the car stereo's speaker wires and
converts them to low level, high impedance signals to
be used by the amplifier. Install the converter according
to the manufacturers' instructions.
The colors of the jacks on the RCA
cables and adaptors shown here
are for illustration purposes.
The color of the cables and adaptors
that you purchase for installation will
vary by manufacturer.
You must trim the unused speaker wires on the stereo and
wrap with electrical tape as shown to prevent a short circuit.

What is the per channel RMS power of this amplifier?
50 Watts RMS per channel times two channels. Consult the specifications in the installation manual.
What is a 3 Way Electronic Crossover?
A 3 Way Electronic Crossover divides the audio signal into two parts. This permits you to customize the amplifier
to power a subwoofer (BASS), or a pair of satellite tweeters like the Roadmaster RT-15 (TREBLE).
When the switch is set to FLAT the full audio signal will power a pair of full-range speakers.
Can I hook up two speakers to this amplifier?
The VRA2.0 is designed to operate two full-range speakers, one on the left channel and one on the right channel.
It can drive two single voice coil subwoofers, one on the left channel & and one on the right channel.
It will also drive a dual voice coil subwoofer, with one coil connected to the right channel, and one voice coil
connected to the left channel.
Can I wire a bridged subwoofer ("Bridge" two channels)?
Yes, you can connect a subwoofer by bridging the two channels, see Speaker Wiring and Options.
What if my car radio doesn't have RCA line outputs?
You will need a converter used to change the signals from the speaker wires to RCA line level inputs. Follow
the converter manufacturer's installation instructions.
What should I do if my car radio doesn't have a remote wire?
Connect the amplifier remote terminal to a switched 12 Volt circuit controlled by the ignition switch. This will turn
the amplifier off when the ignition switch is turned off.
Do I need a stiffening capacitor with this amplifier?
It never hurts to have extra reserve power when operating an amplifier of this caliber.
The VRPC1000 Power Capacitor is the perfect companion to the VRA2.0 Amplifier.
Why does the Power / Protect LED switch between green & red?
Check your POWER and GROUND connections. Also check to see that your wire size is sufficient to
carry the current demand. Check for improper impedance loads (especially if bridging two channels into one.)
Why does the Power / Protect LED stay red?
This typically indicates that one or more of the MOSFET output transistors has shorted.
This condition will not fix itself. The amplifier must be returned to Virtual Reality Sound Labs for repair.

The VRPC1000 Power Capacitor is the perfect companion to the VRA2.0 Amplifier.
Why does the Power / Protect LED switch between green & red?
Check your POWER and GROUND connections. Also check to see that your wire size is sufficient to
carry the current demand. Check for improper impedance loads (especially if bridging two channels into one.)
Why does the Power / Protect LED stay red?
This typically indicates that one or more of the MOSFET output transistors has shorted.
This condition will not fix itself. The amplifier must be returned to Virtual Reality Sound Labs for repair.
