Recommendation
A power subwoofer’s performance is only as good as its installation. Proper installation will maximize the system’s overall performance. It is recommended that you have our product installed by an authorized Euphoria™ retailer. However, if you decide to install it yourself, please carefully read through this manual and take your time to do a quality installation.
Optimal Product Choice
To get the Maximum performance out of your stereo system, we recommend using 100% authentic Euphoria™ electronics and DB LINK wiring and accessories. Matching Euphoria amplifiers and Speakers with your state-of the art electronics purchase is critical to optimize your system’s performance. Wiring is the lifeblood of a system, make sure your audio system has the adequate current and signal transfer it deserves and needs. DB Link has it all, from wiring rolls; Speaker, power, ground and remote to amplifier kits, RCAs, and Fuse holders, distribution blocks and battery connectors. Insist on getting the best, DB LINK. It’s what you deserve to get the optimum performance from your audio System.

IMPORTANT!
Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system.

WARNING!
Exposure to high power sound system can cause hearling loss or damange. Listenin to your system at loud levels while driving will impair your ability to hear traffic sounds and emergency vehicles. Use common sense when listening to your system.

RECOMMENDED ENCLOSURE

The purpose of the information below is to help you select the most appropriate type of enclosure for your application. We have selected the two most popular enclosure types and their performance benefits. Sealed Enclosure (Air-Suspension design): Characteristically simpler to make, sealed enclosures usually are better at controlling the woofer’s excursion and performance at lower frequencies. The added control allows for higher power handling or use of a bigger amplifier. The secret is to maintain a perfect seal. Using Glues and sealants at all seams is recommended to prevent leaks and integrity of the enclosure. The size or volume of the enclosure will directly affect the performance of the woofer. Smaller enclosures generally provide the desired bump to the frequency response curb and Greater SPL. Larger enclosures will provide a lower but flatter response for deeper bass. In general, the benefit to the sealed enclosure versus a ported enclosure is a smaller foot print, simpler build with higher power handling, a more linear flat response, superior sound quality and extended low frequency output.
Ported Enclosure (Bass-Reflex or Vented): A ported enclosure is simply a sealed enclosure with a port or vent added to the sealed design for the purpose of tuning the enclosure to higher output at the desired tuned frequency, typically 3db or higher. Another advantage of a ported enclosure is the reduction of cone motion for the speaker, thus distortion at higher power levels within the tuned frequency response of the port. A drawback is that building a ported enclosure is more complex than sealed. Having the wrong port or vent could result in poor sound, and the potential of damaging a woofer when played too loud or out of the tuning frequency. Thus we recommend not guessing, please follow the guidelines listed in this manual or go to a professional. In General, the benefit of a ported enclosure versus a sealed is higher volume output at the
tuned frequency, stronger bass output with lower power input.
Construction: We recommend using ¾” MDF (Medium Density Fiberboard) for the construction of an enclosure. It is critical for the side walls of the enclosure not to flex due to the pressure generated by the woofer, bracing might be required. The enclosure sides should be secured together with nails/screwed. We also recommend the use of glues and sealants to maintain the integrity of the enclosure and eliminate leaks.

CALCULATING ENCLOSURES

• It is difficult to give exact box dimensions that are universal for all cars and trucks. It is for this reason that you must be able to calculate the space in which you have available in order to achieve the proper air volume required.
  It is recommended to build your enclosure from 3/ 4” thick MDF (medium density fiberboard).
  Make sure the enclosure is sealed airtight.

• Calculating External Volume
  To calculate box volume, measure the outside Width x Height x Depth of the enclosure. Example 12” x 14” x 9”=1512 ÷ 1728” Cubic feet
  Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inches total by 1728”. Example 1512 ÷ 1828=.875 Cubic feet

• Calculating Internal Volume
  To calculate the internal (net) volume of the above box you must first multiply the thickness of the wood you are using by Two(2). Example 3/4” x 2= 1.5“ Next subtract 1.5 from each of the outside measurements of the box. Width| Height| Depth
  ---|---|---
  12 – 1.5 = 10.5| 14 – 1.5 = 12.5| 9 – 1.5 = 7.5

• Multiple the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = .5696 Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inch total by 1728”.
  Example 984.375 ÷ 1728=.5696 cubic feet.

DVC WIRING CONFIGURATIONS

You can change the wiring configuration of your speakers (Series, Parallel and Series / Parallel) to match the impedance loads that maximizes the power output of you amplifier. Wiring the same woofer or multiple woofers in these three different wiring configurations will result in different impedance loads.

• Series: Is the method of wiring of alternate positive with negative terminals (string method) (Illustration below)
• Parallel: Is the method of wiring where you wire match 2 speaker terminals with positive to positive terminal and negative to negative. (Illustration below)
• Series/Parallel: This configuration is a combination of both series and parallel. We recommend series for the terminal and parallel for the leads to amp. (Illustration below)
