Here's the response from the horses mouth..... Subject: SEEG rear speakers
Hello J.C.,
The Road Rumble 40(r) would not be compatible with the SEEG radio because
Harley-Davidson radios do not have low level RCA outputs that this amplifier
is designed to utilize.
The Amplified CD radio used on the 2004 Screaming Eagle Electra Glide
FLHTCSE is unique to this model motorcycle. The SEEG radio has 4 ohm
speakers in the fairing and an Enhanced Sound System (ESS) amplifier
contained inside the radio driving the speakers. All other stock (non SEEG)
radios use 8 ohm speakers.
The SEEG radio differs in other ways from the Ultra and Classic radios. The
outputs from the standard radio amplifiers are internally diverted from the
black radio connector to the internal ESS amplifier. This leaves the
standard speaker output wires in the interconnect harness in the fairing
with no output. As a result, rear speakers can be added but, not as easily
to the SEEG motorcycle as to other models.
To add rear speakers to a SEEG:
* Install the King Tourpak and Four Speaker ESS kit, part number 77194-02A.
* The 2004 Amplified CD SEEG radio must be replaced with a 2004 Classic
radio, Harley-Davidson part number 76164-04.
NOTE: Remove the CVO Audio harness and 15A radio amplifier fuse in the fuse
panel (harness includes a 23 pin Grey connector, speaker wires, ground wire
to left ground stud and power wire from the fuse block). This wiring harness
is no longer needed and should be removed from the motorcycle when the ESS
harness is installed.
Using the wrong speaker wires (a possibility if the CVO audio harness is not
removed) will result in a no sound condition. Locate the interconnect
harness speaker wires which were previously unused and taped out of the way.
Connect them to the newly installed ESS wiring harness per the instruction
sheet. These speaker wires are LTGN/W and W/O on the left side and LTGN/BK
and GY/R on the right side. Using these wires will route the output of the
new Classic radio to the Four Speaker ESS amplifier.
If you have any further questions, I will be happy to assist you.
