Thank you for purchasing this FLI UNDERGROUND subwoofer enclosure. It will

provide you with years of trouble free usage providing you follow a few simple

guidelines.

INTRODUCTION

This instruction manual is for your safety and must be adhered to at all times. Please read and

ensure that you fully understand the installation and set up procedures as explained. If you are

unclear on the installation or set up of your FLI UNDERGROUND subwoofer enclosure please

contact your nearest authorised FLI UNDERGROUND dealer.

WARNING

DO NOT EXPOSE THIS PRODUCT TO DAMP OR MOISTURE - doing so may result in fi re,
shock or damage to the product.

BEFORE WIRING DISCONNECT THE CABLE FROM THE POSITIVE BATTERY TERMINAL

- failure to do so may result in electric shock or injury.

ENSURE GOOD AND CORRECT CONNECTIONS - failure to make the correct connections
may result in fi re or damage to the product.

KEEP THE VOLUME AT A LEVEL SO YOU CAN STILL HEAR OUTSIDE NOISE - failure to do
this may result in an accident. FLI UNDERGROUND equipment is capable of producing sound
levels that can permanently damage your hearing. FLI UNDERGROUND recommends caution
when listening at high volume. For safe and enjoyable listening the sound should be comfortable
and clear without distortion.

CAUTION

• Never connect any speaker lead to the car chassis. This can cause severe damage to your
speaker / car radio / amplifi er.

• Before drilling or cutting any holes, investigate the layout of your vehicle thoroughly.

• Use caution when working near the fuel / hydraulic lines and electrical wiring.

• Observe the correct polarity when wiring, improper phasing may cause a loss of bass
response.

• Ensure that no moving parts catch on the speaker or grill (e.g. window or door handles, or
window glass inside the door)

INSTALLATION

• The quality of the installation will affect the system performance and reliability.

• Contact your nearest authorised FLI dealer if you are unsure about the installation of this
product.

• Please mount this unit away from any potential hazards.

• Minimising the length of wires will provide higher audio output from the system.

• The speaker should be securely fastened to the mounting position using the screws
provided.

• Pre drill your mounting holes using a drill and position with the template provided.

• Be sure to investigate your mounting area thoroughly for electrical wires, brake or fuel lines or
fuel tank to prevent causing any damage.

Run in procedure

FLI recommends that you follow the run in procedure for the subwoofer detailed
below.

When your subwoofer is used for the fi rst time naturally like most brand new items it is very
stiff and rigid, it will take time for the moving parts of this subwoofer to loosen up before it
will be ready to deliver its full potential.

For the fi rst 30 hours it is recommended that you play the subwoofer initially at low to medium
volumes, gradually increasing the volume level as time progresses. As a guide, if you listen to it for
1 hour every day it will take a month for the speaker to run in properly. You will notice a big change
in the sound of the subwoofer over this period, as the spider and surround begin to run in the sound
will get deeper and punchier, also the output of it will increase as the suspension loosens up.

A new subwoofer is like a new car engine, it needs a few thousand miles before you can drive it to its full
potential, driving it into the ‘red line’ from the fi rst day will mean engine damage is certain and will not be
covered by warranty and the same applies to the subwoofer. Failure to follow this simple procedure is the
most common reason for a subwoofer to fail after a very short period of time.

Installation

The most common place to mount a bass enclosure is in the luggage compartment of the vehicle. Where in
the luggage compartment it is mounted will have an effect on the sound produced allowing the user to tailor
the sound to best suit their musical tastes. For example if the enclosure is mounted facing the rear bumper,
the bass produced will be noticeably deeper than if it is fi red into the rear seat.

Do not be afraid to experiment with positioning as a little time and effort can yield great improvements in
sound.

Active enclosure Installation

Your FLI UNDERGROUND enclosure is designed with a swift installation routine in

mind. Please mount the enclosure in a dry location on a solid surface. NEVER mount the

enclosure upside down, this will cause the amplifi er to overheat and will eventually damage

the amplifi er. Before fi xing the enclosure in place please ensure that there is suffi cient air

fl ow around the amplifi er heatsink, at least two inches will be suffi cient.

Power Cable

• At least a 10 gauge cable should be used for both the power and the ground connections to the

amplifi er.

• The power cable should be taken directly from the battery. Rubber grommets should be used

when passing through any bulkheads to prevent the cable from becoming chaffed or cut.

• It is vital that a fuse / circuit breaker (of at least equal value to the one fi tted on the amplifi er) is placed

in line with the power cable and is no further than eighteen inches away from the battery.

• Please ensure that the fuse is not fi tted until the entire installation procedure is complete.

• The two tables below are to help you decide on what cable is correct for you. The fi rst enables you to

select the size of cable depending on the length required. The second will help you convert the cable size

from American Wire Gauge to Metric if you need to.
