Attention! Harley Davidson radios come pre-programmed with a preset EQ that cannot be
changed without flashing the radio. Only an authorized Harley Davidson Dealer can flash the
radio and flatten the factory EQ curve. Ask the Dealer to flash the radio to a flat EQ curve. Without
performing this task, the AX-DSP will be distorted and not sound very good.
1. Remove the fairing to access the back of the factory radio. Refer to MetraOnline,
part number 99-9700 for fairing disassembly instructions.
2. Install the AXDSPX-HD2 harness and make all necessary connections, but leave the amp
turn-on wire disconnected.
3. With the arrow stamped onto the cap facing upwards, push the 16-pin connector from
the AXDSPX-HD2 harness into the left side of the cap. The locking clip on the connector
should face upward. Make sure the gasket is seating properly in the cap. (Figure A)
4. With the arrow stamped onto the cap still facing upwards, push the 20-pin connector from
the AXDSPX-HD2 harness into the right side of the cap. The locking clip on the connector
should face upward. Make sure the gasket is seating properly in the cap. (Figure A)
5. Plug the 16-pin and 20-pin connectors from the AXDSPX-HD2 harness into the
AXDSP-X circuit board. (Figure A)
6. Slide the assembly into the case, then click it shut. Zip-tie the enclosure to a secure
location in the fairing to secure it. Make sure the Axxess logo is facing up to further
ensure that no outside elements can enter the enclosure.
