It should take you between 30-45 minutes, depending on your experience with vehicle disassembly. We wonʼt be reinstalling the subwoofer enclosure, so put it away in the garage somewhere.
- Page 3 Youʼll also need to remove the C-Pillars on either side of the rear windshield. Using a panel removal tool or flathead screwdriver, carefully pry outward on the top of the lighting assembly, freeing the top portion. The bottom will simply fold out toward you once the top is free.
- Page 4 Before you get much further, go ahead and pop out the speaker grilles located on either side of the rear deck. You can use you fingers here. Be careful and donʼt force anything. Work your way around from the front of the grille (side closest to you) and around to the sides, being careful not to break the grille.
- Page 5 13mm bolts will be revealed, and youʼll need to remove them using a ratchet or wrench. Notice the four black plastic anchors that run along the width of the bottom edge of the rear deck. (See arrows) These need to be removed. Now the rear deck is free.
- Page 6 Remove the black plastic anchor in the center of the enclosure using your panel removal tool or flat head screwdriver. On vehicles equipped with the factory baby seat tie downs, youʼll also need to remove an additional 3 13mm bolts on the backside of the enclosure. Now, lift the enclosure upward and pull it towards you.
- Page 7 Trunk Disassembly and Wiring Connections: Weʼll first need to remove the Navigation Unit and itʼs trim ring before we can remove the side panel from the car. So, letʼs get started. Using a radio removal tool (available at any auto parts store) insert one tool into each side of the navigation unit.
- Page 8 Conversely, you can also use zip ties to secure the amplifier to the brackets that secure the amplifier/navigation computer. Donʼt mount the new Bavsound amplifier until youʼve made all wiring connections and tuned the amplifier. Since the majority of our wiring connections take place in this same area, the install is a...
- Page 9 Power Connections to your New Amplifier: *Before you make any connections, we recommend disconnecting the negative battery terminal from the battery. This will eliminate any chance electrical damage to the vehicle. Power Wire (Red Wire included in your amplifier wiring kit) Youʼll want to run the large red wire to the positive terminal of the battery.
- Page 10 Once connected at the location above, the ground wire will connect to the GND • terminal on the amplifier. Remote Turn-On Wire: (Blue Wire included in your amplifier wiring kit) Locate the small gauge white wire going into the factory amplifier in the largest plug. Tap into the remote turn on wire with the included blue wire and red butt connector.
- Page 11 After stripping back approximately ¼ʼ of the insulation from the wires, exposing the copper wiring itself, twist one side of the white wire that you cut in half together with the included blue remote turn on wire. Insert these two wires into one side of the butt connector, and crimp tightly. Insert the remaining half of the white wire into the unused side of the butt connector and again crimp down tightly.

- Page 13 Weʼll now need to drop the included bolt/bracket combination through the top of the rear deck to secure the rear of the enclosure. There are several holes in the rear deck where the rear brackets mount, and instead of confusing you with which ones to use, itʼs easiest to “mock”...
- Page 14 From the trunk, weʼll go ahead and attach the quick release bolts to bolts, of course assuming that the enclosure brackets are lined up correctly. Make sure that the bolts are nice and tight and that the enclosure isnʼt able to move.

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.
