FEATURES

Specification

Reference

Sheet

• Vehicle Specific – Custom molded to fit under the rear bench seat.

• 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.

VSPFEXT

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

to protect wires routed through metal.

1. Select the desired location for the speaker terminal cup, and with a hole saw, cut a 2” diameter hole.

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(s) 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 as shown in the diagram and secure the woofers to the enclosure.

Be sure to maintain proper speaker polarity.
