Removal of the door panel / rear side panel /
center protective cover
In order to install the MATCH speakers in the origi-
nal mounting positions it is mandatory to remove
the door panels / rear side panels / center protec-
tive cover.
If you are uncertain how to remove the panels / pro-
tective cover, please either ask your local Mercedes
dealer or an experienced car audio dealer for as-
sistance. In any case follow the instructions of the
car manufacturer.
Please pay attention to the following notes:
1. The cover is fastened with several hidden screws
to the metal sheet of the car. Make sure that you
have loosened all screws before you try to remove
the cover.
2. Additionally the cover is xed by numerous plas-
tic clips, which may be damaged during the disas-
sembly when the ambient temperature is below
10°C. Always pull the cover horizontally to loosen
the clips – never apply any vertical force. Note that
broken plastic clips have to be replaced before rein-
stalling the cover in order to avoid undesired rattle
and noise.
Installation of the UP C42MB-FRT
The UP C42MB-FRT is a 2-way component system,
which will be mounted in the original speaker loca-
tions. After you have dismantled the cover, you can
remove the original midrange speaker. Then con-
nect the mid-woofer UP S4MB-FRT to the original
speaker cable harness and insert it into the original
mounting position. For the installation of the tweeter
you have to remove the mirror triangle that incor-
porated the original tweeter. Extract the original
tweeter and replace it by the new MATCH tweeter
UP S1MB-FRT. If you own a car that hasn’t any
tweeters installed ex works, you have the possibil-
ity to buy the mirror triangles of the Mercedes Bur-
mester sound system as spare parts from your Mer-
cedes dealer. After the tweeter is installed, connect
it to the crossover. Then connect the crossover to
the original speaker cable harness. The crossover
is equipped with a 3-stage tweeter level adjustment.
It allows to adjust the level of the connected tweeter.
Therefore adjust the switch which is located at the
top of the crossover to the desired switch position.
0 dB: The tweeter has the optimum level for most
applications.
-3 dB: The level of the tweeter is reduced by 3 dB.
-6 dB: If you choose this switch setting, the level of
the tweeter is reduced by 6 dB.
Next, the crossover should be properly xed to
the cover, e.g. by using some strong, double-
sided adhesive tape or hot glue. Make sure that you
choose an appropriate recess in the cover as posi-
tion for the crossover network itself, so that it does
not collide with any other part when you reassemble
the cover.
