Congratulations on your purchase of a HYPNOTIC state-of-the-art subwoofer com-

ponent. Your selection of a HYPNOTIC car audio product indicates a true apprecia-

tion of fine musical reproduction. Whether adding to an existing system or including

performance benefits. 

Take this time to attach your sales receipt to the manual and put in a safe place. In

will  be  necessary  to  establish  purchase  date.  For  detailed  warranty  information 

please refer to enclosed warranty card.

A  speaker’s  performance  is  only  as  good  as  it’s  enclosure.    Proper  installation, 

enclosure size and crossover frequency will maximize the overall performance of 

the subwoofer. To properly design and build an enclosure, knowledge of wood -

working as well as the proper tools are required.  We highly recommend that you 

have your enclosure built by an authorized HYPNOTIC retailer. However, if you 

decide to install it yourself, we have included the parameters of each driver and 

recommended enclosure sizes. If after reviewing the enclosed information you have 

any addition questions, please feel free to contact our technical dept.  

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

   1.)  To calculate box volume, measure the outside Width x Height x Depth of

         the enclosure.  

Example 12” x 14” x 9” = 1512” cubic inches

   2.)  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

    1.)  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“

   2.)  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

   3.) Multiple the new totals (H x W x D) 

Example: 10.5 x 12.5 x 7.5 = 984.375

      

   4.) 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.

WARNING!

Exposure  to  high  pressure  levels  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.

While installing your subwoofer enclosure in the vehicle, securely 

fasten it to the frame or floorpan. If the enclosure is not secured 

properly, there is danger of it becoming a projectile in a collision.
