51. REPLACE MIROR SAIL TRIM
Replace the mirror sail trim. Be sure the tweeter pigtail wiring
runs clear at the bottom.
52. MOUNT MIDRANGE/TWEETER CROSSOVER (STEP 1)
The midrange/tweeter crossover mounting is extremely simple - it
is wrapped in water-jet cut foam and is a pressure t into the door
panel. The foam wraps around the crossover with the “T” shaped
section covering the vertical inductor. The foam on the side that
inserts into the door rst (1) should rest on top of the other foam.
The pressure from being inserted into the compartment then
holds the foam and crossover in place.
53. MOUNT MIDRANGE/TWEETER CROSSOVER (STEP 2)
Identify the location for the crossover (see next step). Simply
press t the wrapped crossover into the location.
We’ve developed many different types of crossover mounting for
the doors over the years, this is what we’ve found to be the most
secure, reliable, and the simplest/easiest as well!
54.MOUNT CROSSOVER/CONNECT WIRING HARNESS
The location for the crossover is shown at (1).
Run the wiring harness along the bottom of the door and up to
the factory connection point. Be sure all wiring is clear of the
midrange driver and clear of door panel mounting points. Con-
nect the midrange, tweeter, and factory connectors to the harness
55. REPLACE DOOR PANEL
Insert door lock indicator (1) thru hole. Then align the ve clips
along the top of the panel (2). Wiggle the panel slightly to be sure
all clips are aligned. Give a rm strike over each clip to lock in
place. Repeat for the remaining door clips. TIP: a bit of masking
tape on the panel in the location of the clips can help locate them.
Do not nish re-installing the panel until after testing!

56. SETTINGS
In the vehicle audio settings, center fade and balance, set all bass/
treble and equalization to neutral (no boost or cuts), and turn off
L o g i c 7.
57. SET BASS & TREBLE TO FLAT
From the music control section in the headunit, select TONE ->
BASS. Set the bass level to at (centered dial). Repeat for TREBLE.
These are cricial! Center the BALANCE and FADER
Select TONE -> VOLUME SETTINGS -> GONG. Set the gong vol-
ume to the lowest level. You can adjust this back up to preference
later.
58.SET AUX INPUT LEVELS
If you use any device (mp3 player, sat radio receiver, etc) that uses
a headphone out jack as input to the AUX IN, set the volume on
that device to approx. 80-90% of full volume. Adjust the AUX IN
level setting in the headunit to around 60-80% of full volume.
From the music control section in the headunit, select TONE ->
VOLUME SETTINGS -> AUX INPUT LEVEL and set the level.
59. CONFIRM SPEAKER CONNECTIONS & SETTINGS
In the headunit, turn the Balance control to fade full Left. Start-
ing with a 20Hz tone, play each higher frequency up to about
4kHz. You should hear only the subwoofer rst, then at ~50Hz
you’ll transition to the underseat woofer, at ~150Hz to the mid-
range, and the tweeter at ~2.5kHz. You should hear each speaker
on the left, in the correct order. You may get some sound from
the right, but it should be low level. Fade Balance full Right and
repeat the process. When complete, center Balance & Fade.
60. ROCK. AND ROLL.
Reinstall any remaining trim panels, seats, etc, in the reverse
order they were removed.
That’s it! You should be ready to rock and roll. If you aren’t
seriously impressed by the sound, something is wrong. Trust us
on this. It should be clean, clear, and balanced. If it isn’t, revisit
the steps above or reach out to us for support at 646-926-0011 or
email us at [e-mail].

NOTES
• AMPLIFIER TURN-ON: You will notice that the amplier turns on before the head unit, and remains on
after the head unit is off. This is normal. The sound output system needs to be energized to play your
door chimes, parking distance control sounds, bluetooth, etc. The amp will turn on from the moment
the doors are unlocked or opened, and remain on from between 30 seconds and as much as 20 minutes
after the car is locked. Again, this is perfectly normal. The idle current on the ARC amp is virtually
zero and will not cause any issues with battery drain.
• SIGNAL SOURCE QUALITY: A poor quality signal will always sound poor no matter how good an audio
system is. If you are using MP3s or home-burned CDs it is critical that you understand the limitations
and impacts of digital compression methods. MP3s at less than 256kbps will have noticeable loss of
quality. Satellite radio is also compressed and will have similar quality issues. Non-commercially ob-
tained music (especially downloaded via P2P le-sharing) recordings are often re-mixed by third parties
and will have been compressed in an unknown and uncontrolled manner. If you want good quality
sound, use only commercially obtained CDs or MP3s compressed at 256kbps or 320kbps.
• FACTORY RADIO SETTINGS: Please note that the settings (Bass, Treble, Fade, Balance, AUX input level,
etc.) are stored to each Key FOB & are specic to the Source (Radio, CD, AUX) for many vehicles. You
will need to edit and save the settings for each source and each FOB to have consistent sound.
• PLEASE LISTEN RESPONSIBLY: Your new Integral Audio system is capable of delivering Sound Pressure
Levels that can damage your hearing. It also delivers very clean, low-distortion sound reproduction.
Because distortion sounds bad to your ears, and low-distortion sounds good, you are much more likely
to listen at high levels with your new system. Please exercise caution - we want you to enjoy a lifetime
of great sound!
