DLS SERIES PREPARATION

Installation

Thank you for purchasing the DLS 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).

1. Determine where the speakers will

be mounted. Make sure the area
is large enough for the speaker
to mount evenly. Also ensure the
mounting location is deep enough for
the speaker to fit.

2. Refer to the specification chart to

determine the proper diameter hole
to cut for your speaker model.

3. If needed, use the grille as a

template to mark the locations for
the mounting screws. Drill the holes
with a 3/32" bit.

4. Be sure to observe proper polarity

when connecting the wires. The
speaker's positive terminal is
indicated with a "+" symbol.

5. Fit the speaker to the hole cut-out.

Mount the speaker using the
supplied screws. If the speaker grill
is to be used, insert 4 screws into
the grill holes and then mount the
speaker.
