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.

Safety Considerations
Before starting to mount your speaker, read the mounting and connection instructions carefully. Disconnect the
vehicle battery's negative terminal before making connections. Be sure to observe the safety notes of the Auto-
mobile 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 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.
MULTI-CHANNEL/HIGH POWER
Moving up to a 4x50 watt satellite channel amplifier powering four sets of components and a 2x100 watt sub-
woofer 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 systems

to avoid potential noise pickup. Use braided wire with 2.5 to 4 mm
cable cross section.
