System Connections

First, check the power of the amplifier. If the power of amplifier is higher than the sub-
woofer's rated input power, increase the number of subwoofers so that the power per
subwoofer is lower than the rated input power, or lower the sensitivity of the amplifier.
Supplying power greater than the rated input power of the subwoofer will cause noise
and/or breakage. Also, if using multiple subwoofers, be careful about the total impedance.
Change the connecting pattern of the speakers according to the capable impedance of the
amplifier.
