REFLASHING THE OE RADIO
BC-DSPX-HD2
• Reflashes the OE radio curve to a flat response
• Water Tight Saddle Tramp Case
• 31-band graphic EQ, or 5 band parametric EQ per channel
• Pre-wired for quick installation when retaining the OE radio
• BC-9715 harness with pre-wired inputs and outputs
• Independent equalization for all outputs
• Independent crossover for all outputs
• Selectable slope (12, 24, 36, or 48db per octave)
• Signal Delay
• Settings are adjusted using the AXXESS DSP XL app on Android devices ONLY
• Read, write, and store configurations for future recall
• Password protect feature available in the mobile app
• USB Micro-B updatable Product Information: The Saddle Tramp
DSP is a device that allows a user to flash
the Harley-Davidson® radio to a 4-channel,
flat audio output curve; but when the
device is connected, it locks itself to the
vehicle’s identification number (VIN),
saving the last known state of the radio
into memory. In order to unlock the
Saddle Tramp DSP and use it on a different
vehicle, or return it, you must remove the
flash from the motorcycle, returning the
radio back to factory settings. This can
only be done 3 times in total. In the event
that this product needs to be returned to
the manufacturer, it cannot be locked to a
motorcycle’s VIN.
BC-9715 Harness
• Add an amp harness 2014-up HD with OE radio and fairing
• Provides pre-terminated input and output wires
• RCA output harnesses included
• Pre-wired rear speaker output, used with BC-9720 backbone harness (sold separately)
• Universal for all amps
• Wire covered in protective cloth tape
Reflashing the OE Radio
Stock non-amplified Harley Davidson’s radios use pre-programmed crossover and equalization
settings that are locked into the OE radio. These setting can’t be adjusted without reflashing
your OE radio. Within the Vehicle Selection page of the AX-DSP-XL app you can reflash your OE
radio to output a flat frequency response curve.

BC-DSPX-HD2 INTERFACE ASSEMBLY
Saddle Tramp WR Box Assembly 1
1. Unsnap the Cap from the case. Insert the
overmolded gaskets from the BC-9715
harness into the respective opening in
the front of the Cap, making sure the
grommets are properly seated.
2. Slide the DSP board out of the case and
plug in the 16 and 20 pin connectors.
3. Reinsert the DSP board into the case and
snap the Cap into place. The arrows on
the Cap should be pointed toward the
Saddle Tramp logo on the case.
4. Find a secure mounting location for
the DSP case. It is recommended that
the cap be installed facing down. The
Zip-tie Mounts on each side of the case
can be used to secure the DSP into place.

BC-9715 HARNESS INSTALLATION
1. Unplug the OE radio connector and
install the BC-9715 t-harness. BC-9715 t-HarnessBC-9715 t-Harness
OE Connector removed from radioOE Connector removed from radio
2. The installation of the pre-wired harness is designed to work with multiple styles of aftermarket amplifiers with different
types of inputs and outputs. Both input (white connectors) and output (black connectors) wires on the BC-9715 harness use
Molex terminals that are pre-crimped onto the speaker leads; loose Molex connectors are included to allow the user to pin the
connectors accordingly.
If the amplifier uses Molex Micro Fit connectors for the inputs and outputs, simply match the amplifier’s speaker configuration
and plug them in using the provided connectors.
If the amp uses RCA inputs, pre-terminated Molex connectors with RCAs already wired are provided. The option to hardwire the
speaker inputs and outputs would be the final option.
3. To get battery power and ground wires up the backbone of the motorcycle use Saddle Tramp’s BC-9703 harness. (Sold
separately)
TIP: If you have pinned the Molex Micro fit connector improperly. You will need to use a Pin Extraction tool. (See page 20 for
Troubleshooting tips)

CROSSOVER ADJUST
If installing a subwoofer, the front and rear outputs will default to a 100Hz high pass filter to
keep the low frequency signals out. If a subwoofer is not being installed, change the front
and rear crossover points down to 20Hz for a full range signal, or to the lowest frequency the
speakers will play down to.
Selecting High Pass and Low Pass will provide one crossover frequency adjustment. Band Pass
should only be chosen if installing just front speakers, with one dedicated amp for the
woofers/mids, a second dedicated amp for the tweeters, along with a subwoofer.
Select the desired crossover slope, 24db, 36db, or 48 db. Higher is steeper.

EQUALIZER ADJUST
The front, rear, and sub channels can be adjusted independently within this tab
with 31 bands of equalization available. It is best to tune this by using an RTA
(Real Time Analyzer).
• The Gain slider on the far left is for the channel selected.

MOBILE APP
DELAY ADJUST
Allows a delay of each channel. If a delay is desired, first measure the distance (in
inches) from each speaker to the listening position, then enter those values to the
corresponding speaker. Add (in inches) to the desired speaker to delay it.

INPUTS/LEVELS
Clipping Level - Use this feature to protect sensitive speakers, like tweeters, from being
driven past their capabilities. If the input signal of the DSP clips, the audio will be reduced
by 20dB. Turning down the stereo will allow the audio to come back on at a normal level.
The sensitivity of this feature can be adjusted to the listening preference of the user.
Chime Volume - Not available in this application.
Amp Turn On
SignalSense - Will turn the amplifier on when an audio signal is detected, and keep
on for (10) seconds past the last signal. This ensures the amplifier doesn’t shut off
between tracks.
Always On - Will keep the amplifiers on as long as the bike is cycled on.
Turn-on Delay - This feature isn’t available on 2014-and up Harley Davidson Motorcycles.
Subwoofer Input - For selecting either the sum of the front & rear inputs or the subwoofer
LFE input.
