You'll need:
• Bavsound tool kit (or some variety thereof - the video highlights the tools needed for
this particular installation) -
Interior-Disassembly-Tool-Kit/
• Wire Crimpers
• Metric Wrench / Socket Set
• Tunes in the garage (your choice)
Before you Begin
Please review and familiarize yourself completely with these instructions before
•
starting work on your vehicle!
Ensure that your bass and treble settings are set to their default middle positions
•
before installing your new speaker upgrade. Once you've installed your Stage
1, you can reset the bass and treble settings to taste. Keep in mind that we
generally recommend keeping them both very close to center as large
adjustments introduce distortion into the audio signal and will lower
performance of your system.
Be sure and watch this video, which covers the amplifier connections on your

- Page 2 Locate the three (3) fasteners that secure the driver side carpeted panel to the frame of the vehicle. Using your Bavsound Metal panel removal tool, slide the fork of the tool between the smaller head of the plastic fastener and the larger base, carefully prying outward to slide the center fastener out of its outer casing.
- Page 3 With the fasteners removed and placed to the side, we now need to remove the metal tie down that is located toward the rear of the trunk, closest to the back seat. It is attached to the chassis using a Torx T40 bolt. This needs to be removed as well as the plastic housing that surrounds the bolt.
- Page 4 Now, let’s first remove the two Philips head screws that attach the top portion of the panel. We need to use our Bavsound right angle pick tool to remove the plastic covers on either side of the panel. Once removed, using a Philips head...
- Page 5 With the screws removed, we now need to use our metal Bavsound panel removal tool to remove the four (4) plastic fasteners across the lower portion of the panel. Take note: These fasteners can be VERY tight. Be patient here. Use the same methodology as when removing the trunk carpet liner fasteners.
- Page 6 panel upwards. You may elect to remove the rubber gasket from the rear-most edge of the panel at this point, as it will allow easier removal of the panel. Simply slide the gasket toward you by firmly pulling on it using your hands. It’s time to remove the driver side carpeted panel at this point.
- Page 7 Mounting Location for New Amplifier With everything removed, we now need to decide on a location to mount our new amplifier. Most vehicles have ample room beneath the center floor piece, as shown in the photo below:...
- Page 8 The vehicle shown has a factory installed component present on the passenger side, but as you can see there is nothing mounted on the driver’s side. Here is where we will mount our new amplifier. Place the amplifier in it’s location without mounting it, as we’ll now decide on the appropriate paths for the wiring entering/exiting the amplifier.
- Page 9 Place the amplifier power wire ring over the bolt, and tighten the nut back • down with the terminal on the battery. This is the primary power supply for your new amplifier. This wire will be connected to the +12 terminal on the amplifier.
- Page 10 This wire is connected to the factory grounding connector located on the passenger side of the vehicle in the photo shown below. To attach the ground wire, simply: remove the factory 10mm nut using your Bavsound nut driver • slide the ring terminal attached to the ground wire over the factory bolt •...
- Page 11 Audio Input Connections (Made at factory amplifier) Note the rectangular black box that was included in your amplifier wiring kit. It has 7 total wires coming off it, and for this section, we’ll be using the White, White/Black and Grey, Grey/Black wires. The red, blue, and black wire connections will be covered in the Remote Turn On section.
- Page 12 Here are the factory BMW colors we’ll be working with: -Blue w/Black Stripe (+) twisted with Brown w/Orange Stripe(-) -Yellow w/Black Stripe (+) twisted with Brown w/Orange Stripe (-) Keep in mind that we are essentially “T’ing” into the wires. Tapping into the factory wires using the blue butt connectors, the connections will essentially be as follows:...
- Page 13 Wire Color on LOC Wire Color at Factory Amplifier Grey (+) Blue w/Black Stripe Grey/Black (-) Brown w/Orange Stripe White (+) Yellow w/Black Stripe White/Black (-) Brown w/Orange Stripe At this point, we will cut the factory wires in half, one at a time. We recommend making your connections one side at a time, so as to avoid to any mistakes.
- Page 14 Remote Turn-On Connections: Now, we’ll deal with the black, red, and blue wires on the black rectangular box. These wires must be connected at the new amplifier terminals as highlighted below. Here we will very simply make the following connections. Blue Turn On terminal of new amplifier...

- Page 16 Amplifier Tuning - Remember, watch this video - http://vimeo.com/72214312 Testing the Actual Installation Prior to Tuning First things first, after physically completing the installation, make sure your amplifier is powered up properly. It needs to turn off and on with the key. The power light should turn off when you take the key out of the ignition.
- Page 17 When adjusting the amplifier gains, do everything in very small increments. We recommend 1/8 turn adjustments of the gain to find that sweet spot where there is no distortion and plenty of volume. Everyone listens to music differently, so the tuning process make take some of us days, while others can do it in a matter of minutes, whether they’re a beginner or not.
- Page 18 Amplifier isn’t Powering Up: The fuse wasn’t installed inline on the red 8 gauge power wire at the battery. • This is very often overlooked. Pop in the fuse, and you’ll be good to go. Check to make sure you’ve found the correct remote turn-on wire. This is a very •...
