If you are using two HTI88 sub-
woofers, connect the left
speaker outputs on your
receiver/amplifier to Input 1 on
one subwoofer (or the connec-
tions panel on its back box),
and the right speaker outputs
on your receiver/amplifier to
Input 1 on the second sub-
woofer (or the connections
panel on its back box). Then
connect Output 1 from the left-
channel subwoofer to the
inputs on your main left
speaker, and Output 1 from the
right-channel subwoofer to the
inputs on your main right
speaker. When using the HTI88
in this mono mode, you should
not remove the shorting straps.

Connection Method #2
Use this method when you are
using the HTI88 with a dedica-
ted subwoofer amplifier. Con-
nect your main receiver/
processor’s line-level sub-
woofer output to the line-level
input on your subwoofer ampli-
fier. Connect the speaker termi-
nals on your subwoofer ampli-
fier to either Input 1 or Input 2.
If your amplifier has stereo out-
puts, you may connect one
channel to each of Inputs 1 and
2. However, you must remove
the shorting straps when using
stereo mode. Alternatively, you
may connect each channel to
a separate HTI88. When using
only one input on an individual
HTI88, you should leave the
shorting bars in place.

Using the HTI88BB Back Box
Whichever connection method
you choose, if you are installing
the HTI88BB back box, you will
need to connect all of the eight
wires coming out of the bottom
of the back box to the appropri-
ate terminals on the loud-
speaker. The wires are color-
coded as follows:
