Figure 2 shows connection from a pre-amplifier’s main outputs to the left and right inputs of
your Velodyne subwoofer. You will also need to connect a second pair of RCA cables from the
outputs on the back of your subwoofer to the inputs on the back of your amplifier. When the
subwoofer is installed in this fashion, your satellite speakers will be crossed over at 80 Hz which
removes the lower bass frequencies from your external amplifier and speakers, enabling them
to do a better job reproducing the higher frequencies. By utilizing this method, you will have a
bi-amplified system, gaining improved power and headroom for your system. This installation
method is not as common as the method described in Figure 1. (Cables needed: 2 stereo pair
of RCA cables.)
