Safety Guidelines

Thank you for purchasing the DWS Series car speakers. Although Dual has attempted
to make sure all of the information contained within this manual is accurate, please be
aware that any part of it is subject to change without notice.

The following instructions should be used a general guideline only.
If you are unsure about performing any of the procedures listed
below, please consult a professional car audio installation center.

Before installation, please follow these guidelines:

1. Be sure to carefully read and understand the instructions before attempting to install
this product.

2. For safety, disconnect the negative terminal from the battery prior to beginning the
installation.

3. Use the highest quality connectors for a reliable installation and to minimize signal or
power loss.

4. Use caution before you drill or cut! Be careful not to cut or drill into gas tanks, fuel
lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any
vehicle.

5. Never run speaker wires underneath your vehicle. Running speaker wires inside the
vehicle provides the best protection from exhaust heat and environmental elements.

6. Avoid running wires over, near, or through sharp edged surfaces. Use rubber
grommets to protect any wires routed through metal.

7. When running the speaker cable from the amplifier, avoid running it near sources of
high current (i.e. wiring harnesses, battery cables).

• Connect the speaker outputs from the head unit to the speakers.

• In some vehicles, it may be possible to utilize the existing speaker wiring. When doing

this, be cautious of the polarity (+/-) of the speaker wires, as these wire colors vary for
each vehicle.

Tip: Using factory wiring harness adapters for the head unit and speakers can help
eliminate wiring issues.

• In some vehicles, it may be necessary to run new speaker wire throughout the vehicle.
Observe caution when routing wires.

• Always use quality connectors that fit tightly, or solder each connection. It may be
necessary to waterproof connections made inside door panels.

• Wiring speakers out-of-phase (the polarity of one speaker is wrong) will cause the
speakers to sound poor, and have very little bass response.
