Dual Bandpass Subwoofer System BP104 - Manual (Page 3)


BP1204 INSTALLATION
Installation
The following installation instructions are very basic. If you feel unsure about
installing this speaker system yourself, Dual recommends aquiring the services
of a professional car audio installation center.
Before installation, please review the following guidelines:
1. Be sure to carefully read and understand the instructions before
attempting to install this product.
. For safety, disconnect the battery negative terminal prior to beginning
the installation.
. If additional wiring is required, we recommend running all wires prior to
mounting your speaker in place.
4. To ensure reliable performance and minimize signal or power loss, use the
highest quality connectors available.
5. 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.
6. Never run speaker wires underneath your vehicle. Running speaker wires
inside the vehicle provides the best protection from exhaust, heat and
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, especially the firewall.
8. When running the speaker cable from the amplifier, avoid running it near
sources of high current (i.e. wiring harnesses, battery cables).
9. When connecting the amp, the positive (+) speaker output from the bass amp
connects to the positive (+) terminal and the negative output (-) connects
to the negative (-) input terminal on the input cup located on the rear of
the subwoofer enclosure. DO NOT CONNECT AMP OR ANY AUDIO SOURCE TO
ILLUMINATION INPUTS, AS DAMAGE TO LIGHTS WILL OCCUR.
10. For the illumination connection, the positive (+) output from your 1V system
connects to the positive (+) input and the negative (ground) connects to
the negative (-) input on the input cup located on the rear of the subwoofer
enclosure. Improper 1V polarity will not cause damage to the lights, but they
will not illuminate.
