Installation

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 fixed 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 (If the original cable harness pro-

vides only one speaker connection cable, use the 

bypass connection of the crossover to connect the 

mid-woofer). For the installation of the tweeter you 

have to remove the mirror triangle that incorporated 

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 in-

stalled ex works, you have the possibility to buy the 

mirror triangles of the Mercedes Burmester sound 

system as spare parts from your Mercedes dealer. 

After the tweeter is installed, connect it to the cross-

over. 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  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.
