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.
For additional information on the Velocity Product Line visit our internet site at: http://www.velocity.de.
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 sidemaking 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 ensuring 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 mm2 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.

REAR DECK MOUNTING
Rear deck or sail panel installations are easily accommodated with these speakers since the speakers can often drop into factory holes or may require a simple adaptor plate which can be purchased or formed from wood.
FINAL TWEETER INSTALLATION (see page 7/8)
The biggest advantage of Velocity component speakers is their ability, when properly installed, to provide a tonally accurate sound with a wide sound stage but pinpoint localisation of performers. The largest impact over this sound stage is provided by the tweeter location. To determine this optimal location we recommend a simple experiment.
1.Complete all of the installation except for the tweeters (i.e., speakers, crossover and wiring).
2.Have a friend sit in the passenger´s seat while you sit in the driver´s seat, each holding a Velocity tweeter up to the door.
3.With music having good high frequency content, move the tweeters around listening for the best high frequency response yet maintaining a good left/right acoustical balance in the car.
Mounting the tweeters mid level and as far forward in the door panel is often the best acoustical location in most cars. In most cases, the preferred location usually has the tweeters facing the opposite occupant in the car.
4.Enjoy the music, with good tonal balance and good staging in your car.
