Amplifier Installation
1. Remove the windshield, outer fairing shell, vent below windshield,
fuel tank and seat.
2. Remove and replace the stock metal tray above the radio with the
J&M Amplifier mounting tray by removing the 4 screws holding
the tray to the radio, 4 screws holding the tray to the speaker
enclosures, and 2 screws holding the tray to the gauge assembly.
Place the J&M Amplifier mounting tray in place of the stock tray
and secure with the screws removed from the stock tray. (Figure
B)
3. Mount Amplifier to the J&M Amplifier mounting plate with the 4
screws provided. The 2 shorter screws go toward the gauges.
4. By following the factory wiring harness, route the amplifier power
harness from the fairing, under the fuel tank, and on to the
battery. (removal of the fuel tank is required )
5. After first disconnecting the negative battery cable from the
battery, connect the positive (red) lead from the amplifier
power harness directly to the positive post of the battery. Then
connect the negative (black) lead from the power harness to the
same bolt/stud on the frame that the negative battery cable is
connected to. Then reconnect the negative battery cable to the
battery. (Figure A) Do not connect the negative (black) lead from
the amplifer to the negative post of the battery.
6. Make speaker and Amplifier connections per diagram. Note:
Tweeter rings will now be plugged into the supplied ROKKER XX
Extreme harness instead of the 6.65 speaker. (Figure B, C and D)
Important Programing Note:
The amplifier gain & frequency response
adjustments have been pre-programed at our factory for this specific Harley
Davidson audio system application, using speakers with an impedance of
2-ohms, to provide maximum performance at highway speeds. Should speaker
impedance change, an alternate software programing package will need to be
downloaded & flashed to the digital signal processor inside the amplifier. This
programming service is available direct from ‘J&M Corporation in Tucson AZ
USA. Send email direct to ROKKER_DSP_Pro@jmcorp.com
