Placement of the Speakers
In your car there are many locations to install Rainbow loudspeakers. However you should pay attention to the
following facts: Woofers need a certain volume for the acoustic reproduction. A rear package shelf with a large
boot or doors with a large insulating air cushion are ideal. The necessary minimum volume is also guaranteed if
they are installed in locations in the dashboard or the side panels of the rear package shelf intended for this purpose.
If you want to install the CS-220 X-Plain into the door, make sure that the door covering has been modified and
reinforced.
Please check the suitability of the installation places before you start installation. Don't cut any of the car's
structural frame. Pay attention to the mechanism of the windows and door handles. If installed in the rear, be sure
that the filler neck and the petrol tank are not damaged. You must always pay attention to cables and wires that are
run hidden in your car. Don't cut or damage them. The loudspeaker grilles can help you to find a suitable
installation place by using them as templates on the doors or the rear package shelf. If you have experience with
electrical and mechanical procedures, you can install Rainbow loudspeakers on your own.
For acoustic reasons the components should be arranged as close together as possible. If the distance between
tweeter and woofer is too large, an acoustic hole is the result which leads to a bad sound reproduction.
In-Door Installation
To get a good front-staging the tweeter mustn't be placed too low in your car. Suitable installation places are the
corner of the mirror and the upper part of the door. To get a good woofer performance or kickbass, the whole door
volume must be reinforced. Cut the interior foil of the door covering around the installation place of the woofer and
fasten it in order to prevent its vibration. It is also very important that the area around the woofer is sealed in order
to avoid acoustic short circuits.
The sound deadening of the door panel can help to improve the sound. Use noise-damping material. Should the
door covering tend to vibrate it must be reinforced. If this is not possible you can achieve noise rejection by using
foamed material.
