Section 3 - Adding a Second XM160-2 to the Bike - Cont.
If installing the second amp in a Road Glide or RG Ultra, the second amp will "stick" to the
front of the mounting plate as shown in Fig 3.2 below.
Figure 3.1
IMPORTANT: In this install, we refer to the "1st amp"
as the Primary and the 2nd amp as the Secondary.
On Street Glide/Ultra, the Primary Amp is on the
left side of the plate. On Road Glide/RG Ultra,
the Primary Amp is on the back side of the plate.
In all cases, the Primary Amp is what is powering
your front fairing speakers and the Secondary is
powering speakers elsewhere on the bike.
4. Locate the "input link" harness included in the box. Take the blue 4 pin male plug on the
"input link" and plug into the empty blue 4 pin female plug on the Primary Amp's input
harness. The 8pin plug on the input link will now plug into the "input" on the Secondary
Amp. This is how we get music from the Primary Amp to the Secondary Amp. When done,
you will have a blue 4 pin female plug on the input link that is empty. Although not used
for this install, this empty plug could be used to send music to a 3rd amp later on.
5. The last connection to the secondary amplifier (right side on Street Glide or Front amp
on Road Glide) is to the second set of speakers in the system.
If you are using replacement lids or modifying the lids to hold a speaker, the harness
that comes with the lids will work its way up the bike, and plug right into the 4 pin black
amplified out "pigtail" on the Secondary Amplifier.
