INSTALLATION/OWNER'S MANUAL  
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 1ꢀV 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 1ꢀV polarity will not cause damage to the lights, but they  
will not illuminate.

Enclosure Guidelines  
To achieve the best possible sound from this subwoofer enclosure, Dual  
recommends aquiring the services of a professional car audio installation center.  
If you feel confident in your ability to install this product without the assistance of  
a professional, please read this section thoroughly. We have provided a number  
of placement recommendations and installation tips to assist you. Keep in mind  
that these are provided as a guideline and you may find that other placements  
may provide better results for your specific vehicle.  
• Make sure all moving parts and factory electrical wires are out of the way and  
will not interfere after installation.  
• Ensure the wire is of sufficient length to avoid pulling or stretching. This is even  
more important if the wires will be run under or through the factory interior.  
• Use electrical tape and wire ties to ensure all wires are properly secured.  
• Avoid installing speakers or electronics where they can be subject to moisture.  
• Ensure the speaker wires are connected using correct polarity. The positive  
polarity is marked by a (+) sign. Incorrectly connected subwoofers will result in  
limited bass output.  
• Ensure the Illuminite wires (1ꢀV) are connected using correct polarity. Do not  
connect an amplifier or any audio output source to the Illuminite inputs, as  
doing so will cause permanent damage to the lighting elements.  
• Speaker wire should be isolated from the vehicle’s electrical system to avoid  
noise being picked up by the amplifiers.  
• We recommend using 14 gauge or larger sized speaker wire to ensure your  
subwoofer receives the full power output of your amplifier.  
• Remember to listen responsibly and respect your ears. Being exposed to  
sounds over 1ꢀ5dB for even short periods of time can create permanent  
hearing loss!

Illuminite™ Lighting Hook-Up  
Dual’s patent-pending Illuminite bulb system and control circuitry provide for  
extraordinary blue illumination, allowing for creative, color-coordinated  
installations. The interior of your vehicle will never sound or look ordinary again!  
Let your imagination take you there.  
The lighting features of all Illuminite products require a 1ꢀV power source to  
operate. The speaker has two distinct sets of input terminals. The first is labeled  
"audio input" and the second is labeled "Illuminite lighting inputs". The inputs are  
clearly marked with a label positioned directly above the terminal housing. The  
polarity (+ and -) indicators for each set of inputs also appear on these labels.  
1. Do not connect your amplifier or any audio source to the Illuminite inputs.  
These inputs are designed for switched 1ꢀV DC power only. Do not connect  
directly to your battery permanently, as it will cause your battery to discharge.  
Please use a switched 1ꢀV source.  
ꢀ. See Fig. 1a, (illustrated wiring diagram) to be sure to maintain polarity. Be  
sure to connect to a switched 1ꢀ volt source. Proper connection would be  
the positive (+) 1ꢀV wire to the positive (+) Illuminite input terminal and the  
negative (-) Illuminite input terminal to a solid chassis ground.  
DO NOT CONNECT AMP OR ANY AUDIO SOURCE TO ILLUMINATION INPUTS.  
DAMAGE TO LIGHTS WILL OCCUR, AND WARRANTY WILL BE VOID!

parts inside or attached to the speaker assembly. The BP1ꢀ04 is a sensitive  
electronic device. Removal of or tampering with any part of the speaker and/or its  
assemblies will damage the product and void the warranty.
