Removal of the door panel and tweeter protec-
tive cover
In order to install the MATCH tweeter upgrade kit it
is mandatory to remove the front door panels and
mirror triangles.
If you are uncertain how to remove the panel / 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 re-
move the cover.
2. Additionally the cover is fixed by numerous plas
-
tic clips, which may be damaged during the dis-
assembly when the ambient temperature is be-
low 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 reinstalling the cover in order to avoid un-
desired rattle and noise.
Installation of the UP
T1MB-FRT tweeter
UPGRADE kit
Vehicles without original tweeter:
After removing the door panel and mirror triangle,
disconnect the original speaker cable harness from
the original midrange speaker.
Then connect the “
IN
” connection cable of the
MATCH crossover to the original cable harness and
the “
MID
” connection cable to the original midrange
speaker.
Next, press the MATCH tweeter UP S1MB-FRT into
the original installation slot of the mirror triangle.
If you have a vehicle without tweeter installation
slot, you can purchase a cover with tweeter mount
as a spare part from your Mercedes dealer.
Installation of the UP S1MB-FRT:
Important:
Make sure that all anchoring supports of
the tweeter are correctly engaged.
After the tweeter is installed, connect it to the cross-
over.
Vehicles with factory installed tweeter:
Disconnect the original speaker cable harness from
the original tweeter. Then extract the original tweet-
er out of the mirror triangle and replace it by the new
MATCH tweeter UP S1MB-FRT.
After the tweeter is installed, connect it to the cross-
over. Then connect the “
IN
” connection cable of the
MATCH crossover to the original cable harness.
The “
MID
” connection cable of the crossover re-
mains unused in this case.
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 is driven without volume reduc-
tion.
-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 fixed 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.
