SOUNDSTAGE + SUBWOOFER SYSTEM
FOR 2013+ BMW 3-SERIES (F30) ver. 5/2016

BEFORE YOU BEGIN
2
•Read this Guide completely BEFORE you begin.
•Disconnect the battery negative terminal while working on the vehicle.
•DO NOT PLACE THE KEY FOB in the vehicle with the battery connected and
the seat airbag wiring disconnected. Doing so will set off the airbag light,
and must be reset by your dealer.
•ALWAYS check behind panels and components before drilling, cutting,
or screwing into any part of a vehicle.
•This guide covers several different vehicle models and options. Some
steps only apply to certain installations. Steps images are labeled with
a black bar across the top:
-[SUBWOOFER ONLY] step applies only if you are installing the Integral Audio Subwoofer
System
-If there is no label, the step applies to ALL installations
-Because each kit applies to more than one vehicle, your kit may include extra items.

mounting location, above the drivers-side rear wheel well.
32. ATTACH NEGATIVE TERMINAL TO COMMON GROUND
Use a 10mm socket to remove the nut and attach the ground wire
terminal on top of the common ground terminal.
Route the wire to the back of the amplier mounting area.
33. AMPLIFIER CONNECTIONS (USW CROSSOVER)
With the amplier in place (but still not mounted) so that you can
route the wires as needed, make the following wiring connec-
tions:
• Connect the 6-pole plug on the Signal Wiring harness (shown)
to the USW Crossover mounted underneath the ARC amplier
34. AMPLIFIER CONNECTIONS (POWER & RCA’S)
• Connect Remote Turn-on wire from the Signal Wiring harness
to the ARC amp Remote On
• Connect Positive & Ground power wires to ARC amp power
terminals

ARC Rear RCA inputs
35. AMPLIFIER CONNECTIONS (SPEAKER OUTPUTS)
• Speaker Outputs from Signal harness to ARC amp. The wires
are labeled, “FL++” is Front Left Positive, “FL--” is Front Left
Negative, etc. There are two wires bundled together for EACH
output connection. Make sure that BOTH wires are securely
connected to the terminal.

36. AMPLIFIER CONNECTIONS (FACTORY PLUG)
Connect the plug that was originally disconnected from the facto-
ry amplier to the mating connector on the Signal Wiring har-
ness. Take care when connecting that the pins are aligned and do
not get bent. Slide and lock the locking lever.
37. MOUNT AMPLIFIER
Slide the amplier bracket over the mushroom studs (1) and then
rearwards to lock in place. Secure the amplier to the vehicle
with the nut removed earlier (2). NOTE: if you are also installing
the subwoofer, wait to secure the amplier until after you have
connected the subwoofer output wire (in a later step)
38. REMOVE UNDER-SEAT WOOFER (STEP 1)
Slide the passenger-side front seat all the way back Use a Torx
T-50 to remove the two bolts holding the front of the seat brack-
ets.
39. REMOVE UNDER-SEAT WOOFER (STEP 2)
Now slide the seat all the way forward. Remove the two bolts
holding the rear of the seat.
40. REMOVE UNDER-SEAT WOOFER (STEP 3)
Release seat back to the full forward position. You can now lean
the seat all the way back and it will stay in that position, giving
you access to the underseat area. You may have to move the seat
a little forward or backward to get it to stay. You do not need to
disconnect the airbag connecter (we advise against it), but just be
aware that it is there and take care with it.

remove them and put them back on the Door Sill cover trim. A
panel removal pry tool (2) works well.
44. REMOVE UNDER-SEAT WOOFER (STEP 7)
Pull up the carpet to access the USW enclosure. Use a 10mm
socket to remove the two nuts (1). Detach the wire bundle clip
attached to the top corner of the USW enclosure (2).
Remove the enclosure by lifting up the inner edge rst, then lift-
ing up and towards the middle of the vehicle. Unplug the wiring/
connector by depressing the locking tab in the connector. Remove
the USW enclosure from the vehicle.
45. REMOVE UNDER-SEAT WOOFER (STEP 8)
Place the USW enclosure on a workbench or other solid work sur-
face. Remove the four Torx T-10 screws (1). Starting at the stron-
gest point (2) carefully pry the woofer from the enclosure.

46. MOUNT IASS-8S TO ADAPTER PLATE
Locate the two IASS-8S Shallow Woofers and the F30.USW.HW-K IT
Underseat Woofer Hardware Kit. Mount each woofer to an Adapter
using eight of the #10 x 3/4” Black Screws.
47. HARDWARE SELECTION
Locate the two sets of F30.WH.USW Wiring Pigtails, the four #8-32 x
1” Machine Screws, the four #8 Nuts, and the eight #8 Flat Washers.
48. IASS-8S WIRING
Use the #8-32 x 1” Machine Screws to connect the inner and outer
wiring pigtails. The washers should be underneath the ring ter-
minals on both sides.
Connect the positive and negative wires to the speaker terminals
as shown.
49. INSTALL THE IASS-8S WOOFERS IN THE USW ENCLOSURE
Use the four #6 x 1.25” Pan Head Screws to mount the woofer to
the enclosure (these are the longer, thinner screws with a round-
ed head - don’t confuse them with the cover screws which are a
little thicker and shorter and have a at head).
50. RE-INSTALL THE USW ENCLOSURE
Re-install the enclosure in the vehicle. It may take a little wig-
gling to get the open end (the side towards the door sill) to slide
into its slot. Make sure all wiring is run clear. Replace the two
nuts removed previously and tighten with a 10mm socket.
Connect the USW plug to the factory connector. Replace the car-
pet.

around the bottom of the door rst., then up to the top. Be care-
ful of the door lock indicator - lift the trim panel up and over the
lock indicator.
59. REMOVE THE DRIVERS SIDE DOOR TRIM (STEP 6)
You do not need to remove the door panel trim completely, but
you can if you want. You can leave it attached and prop up the
bottom, or you can disconnect the door handle release and the
remaining wiring and remove the panel completely.
60. REMOVE THE FACTORY MIDRANGE DRIVER

66. CONNECT & ROUTE MID-TWEET HARNESS
Connect the 6-pole plug of the Midrange-Tweeter Wiring Harness to
the mating plug on the crossover.
Connect the plug on the harness (1) to the mating plug on the ve-
hicle (not the tweeter!). Carefully pull open a section of the foam
door liner (2) and route the midrange branch of the harness into
the door and out the midrange speaker cutout.
67. MOUNT IASS-4 TO ADAPTER
Locate the F30.MID.ADAPTER and IASS-4-MS screws in the F30.
MT-XO.HW.KIT. Mount the IASS-4 midrange to the adapter using
the #6 x 3/8” Pan Head Screws.
68. MOUNT IASS-4 TO DOOR
Connect the wiring to the midrange terminals. Using the three
Torx T-20 screws removed earlier, mount the midrange to the
door.
Pull the slack from the midrange wires (just until snug), then
press/re-seal the foam door liner.
69. LOOSEN UPPER DOOR TRIM
Loosen the “mirror sail” portion of the upper door trim. Pull out
on the trim at the bottom of the mirror sail to release the forward
edge, then out and around to release the rear edge (by the win-
dow). You do not need to remove the trim completely, just loosen
enough to gain access to the tweeter behind.
70. REMOVE FACTORY TWEETER
Remove the foam insert. Remove the factory tweeter by releasing
the three plastic catches indicated by the arrows.
