Power Terminal; Remote Terminal; Ground Terminal - Virtual Reality Block Subwoofer Amplifier VRA1.0 Instruction Manual

Read the following wiring instructions very carefully. If you have any trouble understanding
any of these instructions, have the amplifier professionally installed by an experienced
technician. Incorrect wiring will prevent the amplifier from operating, or will damage the
amplifier.
Recommended Method For Splicing Wires
#1
Strip 1/2" of insulation from the ends of the wires..

1. Power Terminal

1. DISCONNECT THE VEHICLE'S NEGATIVE (-) BATTERY TERMINAL FROM THE NEGATIVE BATTERY POST.
2. Strip ½" of insulation from the end of the 8 gauge power wire. Connect the 8 gauge power wire to the
after-market positive battery terminal according to the manufacturer's installation instructions.
To Amplifier Power Terminal
In-line 35 amp Fuse or Circuit Breaker
3. Install a 35 amp fuse or 35 amp circuit breaker in the 8 gauge power wire as close to the battery as practical.
4. Then route the 8 gauge power wire from the 30 amp fuse or circuit breaker to the rear of the amplifier.
5. Strip 1/2" width of insulation from the end of the 8 gauge power wire.
6. Attach a spade lug on the end of 8 Gauge wire.
7. Loosen screw to open POWER connector plates on rear of amplifier.
8. Insert the spade lug between between the connector plates. Turn screw until power cable is tight.

2. Remote Terminal

The REMOTE wire connection automatically turns on your amplifier when your stereo is turned on.
On most stereos, this wire is marked as the REMOTE, ACCESSORY, or POWER ANTENNA.
1. Locate the REMOTE, ACCESSORY, or POWER ANTENNA on the stereo. (Refer to your stereo owner's manual.)
2. Splice REMOTE, ACCESSORY or POWER ANTENNA wire from rear of the stereo to a length of wire that will
reach the rear of the amplifier
3. Loosen screw and open REMOTE connector plates on rear of amplifier.
4. Insert wire end between the REMOTE connector plates.
5. Tighten screw closing REMOTE connector plates on wire.

3. Ground Terminal

1. The ground connection cable should be attached to clean, unpainted chassis metal for a good electrical connection.
2. Find good, non-rusted chassis metal, as close to the amplifier as possible.
3. Drill a pilot hole with a 1/16" drill bit.
4. Use sandpaper to expose an area of bare metal around the pilot hole about the size of a dime.
5. Tightly fasten the provided ground cable with the self tapping sheet metal screw to the chassis metal.
A loose ground will cause distortion and popping noises in the speakers.
You may purchase shielded RCA cables that have a remote wire that is built right into the cable.
This type of cable makes it possible to route both RCA cable and remote wire at the same time.
Recommended Method For Attaching Wires to Terminals
1. POWER WIRE
When connecting the power wire, place
the spade terminal under the contact plate
and the forks around the screw.
tighten the screw.
2. REMOTE WIRE
To connect the remote wire, place the
twisted end under the contact plate and
tighten screw.
3. GROUND WIRE
To connect the supplied ground wire,
remove the screw and contact from the
ground terminal on the rear of the amplifier.
Put the screw through the contact plate,
then through the ground wire, and finally
tighten the screw.
