If you are an enthusiast that plays your system loud and hard, the SPLX
Woofers will take you to the next level. Capable of working in small
enclosures for audiophiles and large vented for SPLX Max “Bass Heads”,
this is woofer was a great a choice if you are serious about your sound.

We ask that you take a moment to read through the entire manual
before installing the woofer to familiarize your self with the connection
procedure as well as determining the best fit enclosure for you and your
vehicle’s application.

Building the Enclosure

First determine the dimensions of your enclosure. Be certain the box
dimensions that you have designed will fit in the locations you have
chosen. Sometimes, making a cardboard box with the identical outer
dimensions is helpful to confirm it will fit properly. We recommend using
.75” thick MDF (Medium Density Fiberboard) to build your speaker box
with.

Use a “T-Square” to verify you have cut all your precise right angles
before you assemble the box completely. Use high quality wood glue
along with nails and screws for proper assembly.

Apply a sealant to all of the inside corners of the enclosure to assure
proper sealing of the box.

It is recommended to stuff a sealed enclosure with approximately 50%
fill (DACRON or Polyester Insulation) for damping purposes.

Strip off approximately .5”/13mm of wire insulation to assure the bare
wire lead penetrates all the way through the push terminal. Follow by
using additional sealant around the wire lead exiting the enclosure or
around the terminal cup if one is being used.

The following page explains a few different methods for you to match
the impedance of the woofer(s) to the optimum or near best capabili
ties of your amplifier. It is your responsibility to calculate the correct load
for your amp. Please take a moment to read through the diagrams to
insure maximum performance of your woofers and amplifier(s).
