Match MS 83C-BMW.1 Manual page 9

Removal of the door panel
In order to install the MATCH speakers in the ori-
ginal mounting positions it is mandatory to remove
the door panels.
If you are uncertain how to remove the panels,
please either ask your local BMW dealer or an ex-
perienced car audio dealer for assistance. In any
case follow the instructions of the car manufacturer.
Here are some important hints:
1. The door panel is fastened with several hidden
screws to the metal sheet of the door. Make sure
that you have loosened all screws before you try to
remove the door panel.
2. Additionally the door panel is fixed by numerous
plastic clips, which may be damaged during the
disassembly when the ambient temperature is be-
low 1
ooc.
Always pull the door panel horizontally
to loosen the clips- never apply any vertical force.
Note that broken plastic clips have to be replaced
before reinstalling the door panel in order to avoid
undesired rattle and noise.
Installation of the MS 4C-BMW.1
The MS 4C-BMW.1 consists of a 2-way component
system, which will be mounted in the original spea-
ker locations. After you have dismantled the door
panels, you can remove the original midrange spea-
kers. Then reinstall the new MATCH midwoofers,
using the included screws.
For the installation of the tweeters you have to re-
move the mirror triangles that incorporated the ori-
ginal tweeters. Extract the original tweeters from
the triangles and replace them by the new MATCH
tweeters. If you own a car that hasn't any tweeters
installed ex works, you have to buy the appropriate
mirror triangles as spare parts from your BMW dea-
ler first before you install the MS 4C-BMW.1.
After the installation of the midwoofers and the
tweeters you have to connect them to the crossover
network using the included cable harness. Please
note that all wires from speaker to crossover net-
work are already pre-assembled with cable shoes
that can simply be fixed using a Phillips-head screw
driver. Carefully check for the right polarity of each
connection.
Then you have to fix the crossover network to the
door panel, e.g. by using some strong, double-
sided adhesive tape or hot glue. Make sure that
you choose an appropriate recess in the door panel
as position for the crossover network itself, so that
it does not collide with any other part of the door
structure when you reassemble the door panel.
Finally you have to connect the original speaker
cable to the input of the crossover network. This re-
quires cutting off the original connector with pincers.
Never cut the cables directly behind the connector
itself if you like to reconnect them at a later date.
The original speaker cables have to be equipped
with the crimp terminals. These crimp terminals
stick in one of the pre-assembled cables. If you
don't have a dedicated crimping tool you can use
combination pliers for fixing the terminals to the ori-
ginal cables as well.
Installation of the MS 4X-BMW.1
The MS 4X-BMW.1 is a 2-way coaxial system,
which will be installed in the original midrange
speaker positions. After you have dismantled the
door panels, you can remove the original midrange
speakers. Then reinstall the new MATCH coaxial
speakers, using the included screws.
After the installation of the speakers you have to
connect them to the inline crossover networks. Fi-
nally you have to connect the original speaker cable
to the input of the inline crossover network. This re-
quires cutting off the original connector with pincers.
Never cut the cables directly behind the connector
itself if you like to reconnect them at a later date.
The original speaker cables have to be equipped
with the crimp terminals. These crimp terminals
stick in the cables of the inline crossover network.
If you don't have a dedicated crimping tool you can
use combination pliers for fixing the terminals to the
original cables as well.
Installation of the MS 8B-BMW.1
The installation of the under-seat subwoofers re-
quires dismantling the front seats of the car, each
fixed by four screws. Next you have to remove the
original speaker grilles, allowing accessing the woo-
fers themselves. Now replace the original woofers
by the new MATCH subs. For proper operation
of the subwoofers it might be necessary to partly
remove the foam around the speaker mounting
hole. After that you have to re-assemble the origi-
nal speaker grilles. Finally you have to reinstall the
front seats. Please double-check that you have tigh
ten each of the four mounting screws of each seat
properly!
