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.

VEHICLE PREPARATION

6. Remove the entire right rear panel from the vehicle. Remove the seat belt bracket
(with a Torx T-50 driver), the (3) Phillips screws used to secure the panel to the
floorboard, and the (9) press-in rivets. (See photo.)

7. Prepare the grille by carefully removing the (9) plastic clips that hold the cargo
pocket in place. Remove the cargo pocket and retainer net from the panel. Secure the
new wire mesh grille by replacing the (9) plastic clips.

8. Remove the (3) bolts from the factory amplifier (if installed) using a 5/16” socket.
Move the amplifier temporarily out of the way. NOTE: It is not necessary to disconnect
the amplifier’s wiring harness.

9. Thread the supplied bolts fully into the VSP enclosure and test fit the enclosure in the
vehicle. Be sure to remove any obstructions for proper installation.

10. Remove the backing from the wax squares and place them under the bolts. Press
down firmly on the enclosure to make an impression of the bolt heads into the wax
squares. Making sure not to move the wax squares, carefully remove the enclosure
from the vehicle.

11. Check under the vehicle for brake or hydraulic lines before proceeding. Using a 1/2”
diameter drill bit, drill the holes through the fender well and the floor board using the
wax squares as your template.

VSP ENCLOSURE INSTALLATION

12. Connect the proper (+) and (–) speaker terminals from the amplifier to the enclosure.

13. The next procedure will require
2 people. While one person is

Enclosure Wall (urethane) Threaded Insert

molded into enclosure

positioning the VSP enclosure,
the second person should
insert the long bolts from the
underside of the vehicle. Put a
bead of silicone sealant
between the car sheet metal
and the washers. Screw the

Fender washer

Split lock washer

3/8” bolt

Bead of Silicone Sealant

Car’s sheet metal

bolts into the enclosure’s
threaded inserts and tighten
them. DO NOT OVERTIGHTEN.

14. After the bolts are tightened, spray rubberized undercoating over the bolts and over
any bare metal. This will prevent the metal from rusting and will prevent the bolts
from loosening due to vibrations.

15. Replace the factory amplifier, the entire side panel and the seat belt bracket.

16. If necessary, fine tune the system to find the proper bass level for your new VSP
woofer enclosure.
