Congratulations on choosing Focal automobile vented box. To gain the best

Included

• 1 x vented box

• 1 x fixing kit (2 x Nylon straps, 4 x metal roll bar, 8 x fixing screws, 1 x template)

Connections

It is essential that correct polarity be observed with subwoofers. Positive is marked in red,
negative in black.

Wiring

The quality and gauge of wire used will have a strong effect on the quality of sound. Focal
Audiomobile recommend a minimum specification of 2.5mm

2

oxygen free copper (OFC) wire
for subwoofers. Ask your dealer for advice on your specific installation. We recommend the use
of Focal FC 300 and FC 500 cables.

Adjusting the cut-off frequency

The ideal cut-off frequency is usually between 60 and 100 Hz. Optimum adjustment can only
be achieved after listening and/or measuring.

Recommended power

Focal Audiomobile subwoofers have high power handling characteristics. It is therefore
important to choose an amplifier powerful enough to drive them properly. An amplifier that is
too small will distort quickly, limiting the level and quality of the sound and eventually causing
damages to the loudspeakers.

THE FOCAL GUARANTEE ONLY APPLIES IF PAGE 11 IS

Warning!

The high output and power handling of Focal Audiomobile subwoofers means that high
sound pressure levels can be reached. We remind you that listening to music at levels beyond
110dB can permanently damage your hearing.

Installation

We have taken time to design a product that will work exceptionally well. To add to this we
have included a fixing kit to ensure the subwoofer remains securely mounted. Please follow
the below mentioned steps to ensure the subwoofer is mounted correctly.

1 - Rear seats must be positioned in their normal fixed position.

2 - Decide the best location possible that suits your automobile and space available. We

recommend the best location for optimum sound quality and most secure is to position
behind the rear seats, in the trunk of the automobile. It can be positioned in either left
centre or right side locations. This will not change the sound quality, as bass frequencies
are not directional.

3 - Ensure the area for subwoofer location is clean and tidy. Any loose objects are removed, as

they could knock and damage the subwoofer, and this is not covered by the warranty.

4 - Once the location has been decided, carefully attach the fixing template with scotch tape

(fi g. 1).

5 - Now mark the screw hole positions for the fixing brackets. (Please verify with template.)

6 - Drill two holes 2 mm for the 4 fixing brackets, at your defined locations. It is advisable

that the drill depth be reduced to a minimum length, so to prevent drilling to deep into the
textile of the seat (fi g. 2).

7 - Now carefully position the brackets and one screw only into place (fi g. 3).

8 - Now take the two fixing straps and thread through and fix the other screws of the fixing

bracket (fi g. 4).

9 - Now place the subwoofer into position, lay the straps around the grille. (these must be

positioned at the extremity of grille, as indicated on diagrame, this ensures the straps do
not interfere with the driver or port tube. Ensure the straps are flat and untangled (fi g. 5).

10 - Attach the straps, and pull tight (fi g. 6).
