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.
FINAL WOOFER INSTALLATION
INSTALLING THE WOOFERS 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 woofers can often
drop into factory holes or may require a simple adaptor plate which can be purchased or formed from wood.
FINAL TWEETER INSTALLATION
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., woofers, 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 frequen-
cy 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.
