INTRODUCTION
Congratulations on your purchase of the world's finest brand of car audio speakers.
We have invested tremendous effort in the design process of the new Velocity speaker series, in order to achie-
ve superior musical performance. For maximum performance and reliability we highly recommend that your new
Velocity speakers be installed by an authorized Velocity dealer.

Safty Considerations
Before starting to mount your speaker, read the mounting and connection instructions carefully. Discon
nect the vehicle battery's negative terminal before making connections.Be sure to observe the safcty
notes of the aotomobile manufacturer (airbags, alarm sx stems, onboard computers, immobilisers). Befo
re drilling holes, look to see what is on the other side- making holes into the battery, wiring looms or fuse
box is not recommended.
SOUND QUALITY VS. LOUDNESS
SOUND QUALITY
A good audio system will faithfully reproduce the original recording by offering accurate frequency response and
staging. Good frequency response reproduces high tones such as cymbals, through human voices and most
instruments, and down to the very low tones from synthesisers and drums. Frequency response includes timbre
(the accurate replication of an instrument), linearity (the tonal quality is the same regardless of volume level),
and clarity (lack of distortion of the original signal). Velocity speakers address these properties by having a very
smooth frequency response with low distortion levels.
Good staging offers the illusion of a stage upon which players are located and it has a sense of height, width,
and depth. Imaging is a sound system's ability to correctly place the instruments on the imaginary stage. Again,
the Velocity speakers excel here due to angled tweeter mounting and smooth off-axis frequency response ensu-
ring accurate reproduction.
MECHANICAL AND ELECTRICAL INSTALLATION
MOUNTING SPEAKERS
The prime objectives of speaker mounting are:
• Positioning the speakers correctly.
• Mounting them to a solid surface
• Protecting the speakers
• Ensuring the wiring is correct
The lower the frequencies a speaker reproduces, the more solid it´s mounting surface must be.
This is necessary because a vibrating panel winds up acting like another loudspeaker and introduces its own
sound into the car. This secondary sound can severely degrade the sound of the music yielding a "muffled" or
"howling" sound at certain listening levels. A good air seal isolating the sound from the back of the speaker from
the front wave sound is critical. Lack of a good air seal reduces the bass response and often creates a "hollow"
sound from the woofer .
The tweeter´s mounting is not nearly so critical since it does not require a rear air seal and it vibrates very little.
Speaker wiring must be isolated from the electrical system of the car and routed away from any factory systems

to avoid potential noise pickup. Use braided wire with 2.5 to 4 mm
cable cross section.
FINAL SPEAKER INSTALLATION
INSTALLING THE SPEAKERS IN FACTORY LOCATIONS
Most of today´s newer cars have speaker grilles which blend in aesthetically with the interior of the car. The grille
is usually held in with small screws or spring clips. To remove a clipped on grille, gently pry up on the side with a
flat blade screwdriver. (Some grilles are an integral part of the door such that the entire door panel must be
removed to expose the speaker.) Once the factory speaker is exposed, remove the hardware and replace the
factory unit with the new Velocity unit.
