1. Separate the three pieces of Foam shown in color.
2. Clean the back panel
of the door, remove the backing paper from the Core and
adhere directly behind the speaker to the outermost panel
in the door. This will help
absorb the rear wave and reduce panel vibration. (This step is optional
as it is
possible to absorb moisture)
3. With a razor blade cut circumferentially the
Middle down to approximately 1/4".
Remove
backing paper and adhere to mounting surface
of speaker. This will decouple the
speaker from its substrate and prevent front and rear wave cancellation.
4. Using standard installation procedures wire and mount speaker.
5. Clean around the outside edge of the speaker, remove the backing paper from
the
Outside Ring and adhere the Outside Ring directly around the speaker. Test fit
panel
for fitment. If needed tr im the Outside Ring circumferentially until proper
fitment is achieved. It should press tightly
to the door panel. This will focus all the
sound into the cabin, prevent panel vibration
and destructive wave interference giving you noticeably improved speaker
performance and less panel resonance.
