CONNECTING TWO ICS Sub 24’s
You may wish to use two ICS Sub 24’s, particularly if you are in a large room.
Double subwoofers may be wired
with either speaker-level or line-level
connections.
Be sure the Phase Switch is set the
same on both units.
To connect two ICS Sub 24’s using line-
level inputs, use "Y" connectors to daisy
chain the ”PREAMP OUT“ signal to the
input of a second ICS Sub 24.

Connect the main speakers
directly to the system's
amplifier to run the main
speakers full range.
Connect the main speakers to the
High Level Outputs to take
advantage of the high pass filter
in the ICS Sub 24 amp.
