Information on running speaker cable through walls, under walkways, patios, etc. is not

included in this manual. If you are not comfortable with this sort of installation, contact a

qualified installer (see your dealer).

Preparing the Cable

Always use high-quality, moisture-resistant speaker cable (see your dealer).

1. Measure and mark path from amplifier to speakers to determine length of cables.

2. Add 2–3 feet (0.6–0.9 meters) extra to allow some play when installing.

3. Select correct gauge using the chart below.

4. If the cable is to be run underground it must be rated for direct burial and/or

enclosed in PVC pipe to prevent deterioration over time (see your dealer).

5. Cut cable to required length and strip outer casing about 2 inches (5cm) on both ends.

6. Strip inner insulation on both wires back about

2-inch (1.25cm) on both ends.

The following chart identifies the minimum gauge requirements for cable by length.

Minimum Wire Gauge Requirements

Length Gauge/Diameter

Less than 15 feet (4.5 m) 16 awg / 0.05 inch (1.3 mm)

Less than 30 feet (9 m) 14 awg / 0.06 inch (1.6 mm)

More than 30 feet (9 m) 12 awg / 0.08 inch (2 mm)

Connecting the Speakers

WARNING! Turn your amplifier off before making or breaking any signal con-

nections. This will avoid damage which could result from accidental shorting

of speaker cables.

Test your speakers before installing the cables! Before permanently installing cable in

your landscaping, place your speakers in the desired location and listen for:

• Volume: Walk around the area and ensure that sound is coming from each

speaker, and that it is balanced throughout the listening area.
