Location

Place the powered subwoofer 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 powered subwoofer 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 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)

1.Power Terminal

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.

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 amplifier.

8.Insert the spade lug 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 the 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.

Recommended Method For Attaching Wires to Terminals
