VSP ENCLOSURE
FEATURES
• Vehicle Specific – Custom molded to fit behind the right rear cargo pocket.
• Acoustic Suspension Enclosure – The VSP enclosure uses an acoustic
suspension design (sealed) for optimum performance. The enclosure is matched
to the woofer for deep bass output while requiring minimal operating space.
• Roto-Molded Urethane Construction – The use of Roto-Mold
manufacturing produces a composite enclosure with seamless construction. This
greatly increases rigidity to prevent the enclosure from flexing and allows custom
designs to be fabricated. The result is a radical, stronger, more reliable
enclosure.
PUNCH WOOFER
• PVA Cone – The cone material used is spruce pulp paper and provides the
necessary combination of weight and strength to allow high levels of output
without cone break up. The cone is also treated with a water resistant PolyVinyl
Acetate (PVA) Emulsion which increases cone rigidity and lowers distortion.

• Aluminum Voice Coil Former – The voice coil is made of
multiple layers of copper wound on a black, anodized aluminum
former. This improves the speaker’s power handling by efficiently
dissipating heat from the voice coil.
• Hyper-Extended Pole Piece – The pole piece has been extended
to provide a more linear magnetic field for the operation of the woofer.
This lowers distortion and provides the woofer with better low frequency
response.
• Vented Bumped Back Plate – The back plate has been stepped
deeper to allow the woofer more excursion for harder hitting bass.
Additionally, the back plate is vented with a radiused aerodynamic vent
that efficiently and quietly keeps the voice coil cool.

Vehicle Specific Punch
VSPEXPL
The Vehicle Specific Punch (VSP) enclosure is supplied in kit form to allow custom finishing techniques. The unfinished surface
enables matching paint or carpet to be applied to the enclosure for seamless integration into the vehicle’s interior. In addition, the
input terminal cup can be positioned in the desired location where speaker wires can be conveniently routed from the amplifier to
the enclosure.

Installation
Reference
Sheet
IMPORTANT – Please follow these instructions carefully!!
The VSP enclosure is specially molded to fit particular vehicles. Be sure to attach the enclosure to the vehicle as
specified in this installation sheet for optimized bass output. Failure to install the enclosure as specified in this document may allow the enclosure to become detached from the vehicle and possibly cause personal injury.
Always use eye protection when drilling.
Never run wires underneath the vehicle. Run wires inside the vehicle and use rubber or plastic grommets
!
VSP ENCLOSURE PREPARATION
1. Select the desired location for the speaker terminal cup, and with a hole saw, cut a 2” diameter hole.
to protect wires routed through metal.
2. Using the speaker terminal cup as a template, mark the holes used to secure the cup to the enclosure.
Remove the cup and drill pilot holes using a 3/32” drill bit.
3. Carpet or paint the enclosure and the speaker grille to your desired color theme.
4. Connect the supplied speaker wire to the appropriate (+) and (–) terminals of the speaker cup.
Connect the RED wire to the (+) terminal and the BLACK wire to the (–) terminal.
5. Secure the speaker terminal cup to the enclosure using the (4) supplied Phillips screws. Connect
the speaker wires to the woofer and secure the woofer to the enclosure. Be sure to maintain
proper speaker polarity.
