Recommendation:
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 a high power sound system can cause hearing loss or damage. Listening
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 ENCLOSURES
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 the use of a bigger amplifier. The secret is to maintain a perfect seal. Using glue 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 of the sealed enclosure versus a ported enclosure is a smaller
footprint, 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 a sealed enclosure. 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 enclosure is higher volume output at
the tuned frequency and 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
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
Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inches total by 1728”. Example 1512 ÷ 1728=.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 = 984.375
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.
It is recommended to build your enclosure from at least 3/4” thick MDF (medium density fiber
board). Make sure the enclosure is sealed airtight.

You can change the wiring configuration of your speakers ( Series, Parallel and Series / Parallel ) to match
the impedance loads that maximize the power output of your 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 wiring in
series for the terminal and parallel for the leads to the amp. ( Illustration below ).
