Stage 1 Audio Upgrade Supplemental Instructions for ‘01-‘03 BMW M5
(E39) with M Audio
Front Speakers:
You will leave the factory midrange in its housing and will reuse it. Do not remove the midrange.
1. Remove the Midbass/Midrange Assembly by first removing the foam from around the speakers.
2. Unscrew the assembly and remove it as one piece. Clip the small wires going from the midbass
driver up through the speaker and into the midrange bridge. Pull these through the midbass driver.
We will be using these again.
3. Note the two sets of wires remaining in the enclosure. We will be feeding the wires that went into
the midrange bridge back through the enclosure via a small hole that will need to be drilled in the
top of enclosure.
The wires that we will be using for this procedure are twisted together inside of the enclosure. Pull
the wires up through the enclosure and make the following connections on the outside of the
enclosure.
• Blue/Yellow Stripe is Positive (+) Æ Black/white stripe wire on midrange bridge.
• Blue/Green Stripe is Negative (-) Æ Black wire on midrange bridge.
When installing the midbass driver, use the following wire colors to connect to the speaker:
• Red/Green Stripe is Positive (+)
• Brown/Red Stripe is Negative (-)
When installing the midbass driver, you’ll first make sure that you’ve sealed the enclosure with the supplied
gasket tape. Set the woofer down into the enclosure, and screw down two of the four mounting points on
opposing sides from one another.
Next, you’ll want to place the included spacers on opposing sides stacked three (3) high. This will allow
clearance for the bridge to sit safely above the midbass driver. The height of the spacers may be less if
you’re using Rainbow Audio drivers.
Here is the finished front Midbass driver installed with the midrange bridge.

There is also a slight variation with the tweeter wire colors from the standard M5 systems…

• Yellow/Red Stripe is Positive (+)
• Solid Yellow is Negative (-)
Rear Speakers
Wire colors for the rear speakers are the same as they are for the front, less the tweeters of course…
• Keep in mind you do NOT have to remove the rear doors. There are no speakers in there. ☺
• We will remove the wires from the midrange bridge in the same manner outlined above.

Rear Midbass Prepartion
When mounting the rear midbass drivers, leave the screw hole closest to the plug on the enclosure empty.
We will attach the tweeter here once the rear deck is installed.
-You will also have to drill a small hole in the rear enclosure to run the wires up to the new tweeter. This will
be done similarly to the front. Note where the hole is being drilled below:
