Please Note: This manual covers multiple models. Parts of the following
instructions may not apply to your installation.
The installation instructions included here are basic. If you feel
unsure about personally installing the speaker system. Dual
recommends that you seek installation by a qualified
sound technician.
Before installation, please follow the following rules:
1. Be sure to carefully read and understand the instructions
beforeattempting to install the product.
2. For safety, disconnect the negative lead from the battery prior to beginning
the installation.
3. For easier assembly, we recommend that if additional wiring is required,
that you run all wires prior to mounting your speaker in place.
4. Use the highest quality connectors for a reliable installation and to
minimize signal or power loss.
5. Use caution before you drill or cut! Be careful not to cut or drill into gas
tanks, fuel lines, hydraulic lines, vacuum lines or electrical wiring when
working on any vessel.
6. Never run speaker wires underneath or on the exgterior of your vessel.
Running speaker wires inside provides the best protection from
environmental elements.
7. Avoid running wires over, near, or through sharp edged surfaces. We
suggest you also use rubber grommets to protect any wires routed
through metal or fiberglass.
8. When running the speaker cable from the receiver or amplifier, avoid
running it near sources of high current (i.e. wiring harnesses, battery
cables).
9. The positive (+) speaker output from the receiver or amp connects to the
red terminal of the enclosure, and the negative (-) connects to the black
terminal.
