Automotive audio equipment installations can be troublesome at times, even to the most experienced of installation technicians. If you are not confident working with electrical wiring, removing and reinstalling interior panels, carpeting, dashboards or other components of your vehicle, please call our toll free help line (800)445-1797 and our in-house technical service team will answer your installation questions.

Tools Needed For Installation:

• Nail Set/Center Punch

• Hammer

• Safety Glasses

• Electrical Tape

• Phillips Screwdriver

• Wire Cutter

• Marker/Pen

• Electric Drill with 1/16" bit

We recommend an Amplifier Installation Kit containing the following parts:

• Power Wire - 8 Gauge w/Terminal Lug

• Speaker Wire - 16 to 12 Gauge

• RCA "Y" Adaptors

• Remote Wire - 20 Gauge OK

• Input Wires - Shielded RCA cables

• After-Market Battery terminal

Location

When choosing a location for the amplifier, keep in mind that the amplifier will generate heat. Place the amplifier in a location that allows for 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 VRA 4.0 amplifier, place the VRA 4.0 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 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 amplifier, if the Power Protection light is green, turn off the amplifier and proceed to the next section. If the Power Protection light is red, review the all of the connections and wires, you may have loose connections, a bad chassis ground, or inadequate size power wire. After reviewing all the connections and wires, and the problem persist, call our toll free help line for assistance.

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.

When mounting the amplifier, make sure there is enough room for access to make adjustments to the switches and adjustment screws.

Read the following wiring instructions very carefully. If you 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

#3

Strip 1/2" of insulation from the ends of the wires..

Twist together and bend as shown.

Wrap with electrical tape.

1.Power Terminal

1.Disconnect the negative(-) battery terminal from the negative battery post.

2.Remove the fuse(s) from the amplifier.

3.Strip Ω" 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 maunfacturer's installation instructions.

4.Install a 30 amp fuse or 30 amp circuit breaker in the 8 gauge power wire as close to the battery as practical.

5.Then route the 8 gauge power wire from the 30 amp fuse or circuit breaker to the rear of the amplifier.

6.Strip 1/2" width of insulation from the end of the 8 gauge power wire.

7.Attach a spade lug on the end of 8 Ga. 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's 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.

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, then 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, then tighten the screw.
