Place the powered subwoofer in a location that allows air to circulate around it. Amplifi er location and installation will vary from vehicle to vehicle
depending on physical layout of the vehicle. Carefully consider as many installation locations and confi gurations as is practically possible DO
NOT COVER the powered subwoofer with carpet or enclose it behind interior panels. DO NOT mount inverted or upside down. The amplifi er
may be mounted vertically.
Before permanently installing your VRA1.0PSW Powered Subwoofer, place the VRA1.0PSW Powered Subwoofer in the approximate place it
will occupy in your car. Run all power and speaker wires inside the vehicle toward the powered subwoofer prior to mounting. This will allow you
to estimate how much wire you’ll need and where to route the wires inside of your vehicle.
Connect the fused 12 Volt DC power wire, chassis ground cable, and remote wires. (SEE SECTION 3, ELECTRICAL CONNECTIONS)
Turn on the car strereo, if the Power Protection light is green, turn off the stereo and proceed to the next section. If the Power Protection light is
red, review all of the connections and wires. You may have a loose connection, a bad chassis ground, or an inadequate size power wire. If the
problem persists after reviewing all of the connections and wires, call our toll-free help line for assistance.
1. DISCONNECT THE 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.
The REMOTE wire connection automatically turns on your amplifi er when your stereo is turned on.
On most stereos, this wire is marked as the REMOTE, ACCESSORY, or POWER
ANTENNA.
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 amplifi er 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.
1. Locate the REMOTE,
ACCESSORY, or POWER ANTENNA on the stereo. (Refer to your stereo owner’s manual.)
2. Splice the REMOTE, ACCESSORY or POWER ANTENNA wire from rear of the stereo to a length of wire that will
reach the rear of the amplifi er
3. Loosen screw and open REMOTE connector plates on rear of amplifi er.
4. Insert wire end between the REMOTE connector plates.
5. Tighten screw closing REMOTE connector plates on wire.
3. Install a 25 amp fuse or 25 amp circuit breaker in the 8 gauge power wire as close to the battery as practical.
4. Route the 8 gauge power wire from the 25 amp fuse or circuit breaker to the rear of the powered subwoofer.
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 the 8 Gauge wire.
7. Loosen screw to open POWER connector plates on rear of amplifi er.
8. Insert the spade lug between the connector plates. Turn screw until power cable is tight.

2. Mounting the Powered Subwoofer
1 Pre-installation 3 Electrical Connections
Do not mount inverted or upside down. Do not cover with
carpeting or enclose it behind interior panels.
Read the following wiring instructions very carefully. If you have any trouble understanding any of these instruc-
tions, have the amplifier professionally installed by an experienced technician. Incorrect wiring will prevent the
amplifier from operating, or will damage the amplifier.
When mounting the powered subwoofer, make sure there is enough
room for access to make adjustments to the volume control.
To connect the supplied ground wire,
remove the screw and contact from the
ground terminal on the rear of the am-
plifi er. Put the screw through the contact
plate, then through the ground wire, and
fi nally tighten the screw.
To connect the remote wire, place the
twisted end under the contact plate and
tighten screw.
When connecting the power wire, place
the spade terminal under the contact
plate and the forks around the screw.
Then tighten the screw.
