APPLICATIONS – CS300.1
The CS subwoofer amplifier is a 
single-channel amplifier. There are 
two sets of terminals to make it easy 
to connect multiple woofers. Either 
set of (+/–) terminals may be used
when connecting woofers.
To the right are two application 
diagrams to help plan your subwoofer
system installation. 
Figures 2 and 3
show how to configure the 
CS300.1 
subwoofer amplifier. 
NOTE: For simplicity, Figures 2 and 3 
do not show power, remote and input
connections.
NOTE: Minimum speaker load is 
2 ohms total.

APPLICATIONS – CS50.4
The CS50.4 can be set up for stereo 
4-channel, 3-channel or bridged 
2-channel operation, as shown in
Figures 4 through 6
NOTE: For simplicity, Figures 4 through
6 do not show power, remote and input 
connections.
NOTE: Minimum speaker impedance
for stereo operation is 2 ohms.
Minimum speaker impedance for
bridged operation is 4 ohms.
