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
achieve superior musical performance. For maximum performance and reliability we highly recommend
that your new Velocity speakers be installed by an authorized Velocity dealer.

Safety 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 safety
notes of the Automobile manufacturer (airbags, alarm systems, onboard computers, immobilisers).
Before 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 re-
sponse 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 ensuring accurate reproduction.
MULTI-CHANNEL/HIGH POWER
Moving up to a 4x50 watt satellite channel amplifier powering four sets of components and a 2x100 watt
subwoofer amplifier powering a Velocity subwoofer can offer stunning performance!
The increase in amplifier power help reduce "clipping" which yields a "cracking" type of sound which can
damage nearly any speaker over time. The tonal accuracy of the system is also often improved because
the amplifiers are no longer strained at high listening levels.
MECHANICAL AND ELECTRICAL INSTALLATION
MOUNTING COMPONENT SPEAKERS
The prime objectives of component speaker mounting are:
• Positioning the speakers correctly.
• Mounting them to a solid surface
• Making sure there are no air leaks between the front and back of the woofers cone
• 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
2
systems to avoid potential noise pickup. Use braided wire with 2.5 to 4 mm
cable cross section.
