Positioning the Loudspeaker
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 windshield
deck 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.
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 windshield deck. 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.
Door Installation
To get a good front-staging the tweeter mustn't be placed too low in your car. Suitable installation places
are the mirror triangle 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.
