Adding a Subwoofer to Juke
Juke provides zone outputs that power speakers in each zone. To add a powered subwoofer to
a zone, connect an adapter in parallel with either the left or right speaker in the room where a
subwoofer will be used. The adapter converts the speaker voltage to line-level so that it can be
connected to the input of a powered subwoofer.
Instructions:
1. Buy two inexpensive items on Amazon or elsewhere (the Rockford Fosgate part converts
the speaker-level signal to line-level, and the Boss part ensures that there is no ground-loop
noise):
a. Rockford Fosgate RFI2SW High Level RCA Input Plug. The Amazon ASIN number is
B009B8EJYU, and the price is about $9.77. Here is the Amazon link: Speaker-level to line-level
converter
b. BOSS Audio Systems Ground Loop Isolator B25N noise Filter for Car Audio Systems. The
Amazon ASIN number is B000LP4RMG, and the price is about $7.80. Here is the Amazon link:

2. Connect two of the four bare wires of the Rockford Fosgate part to two of Juke’s speaker
terminals for the zone where the powered subwoofer is located (you can use the left channel,
but either should be fine). Please note that this adapter must be connected in parallel with a
speaker. If no speaker is connected, Juke senses this and will not provide an output.
3. Plug the corresponding RCA connector of the Rockford Fosgate part into a connector on
the Boss part, then connect the same color RCA connector to the RCA input on the powered
subwoofer.
Here is what the Rockford Fosgate and Boss parts look like when connected together (this
shows both the left and right channels being connected, but only one is necessary):
Adding on Zones
The Juke-6 can be upgraded via a premium software upgrade available on our website to
enable the 7th and 8th zone of the unit. In situations where more than 8 zones are required, you
can combine our units together to reach more zones. As long as the Jukes are connected to
the same network, they will recognize each other and pair wirelessly, allowing you to stream
across the zones together. (12 zones, 16 zones, etc.)
And here is what they look like applied to the terminal block in parallel with the PAC device
(the brown wires are for grounding, which can be ignored, so just apply electricians tape to the
ends):
