Can I connect another subwoofer amp to the low level output?
No you can’t. There is an active highpass filter in the sub amp that rolls off everything below 150 Hz from the signal output here. With this high-pass output, a second sub amp will produce very little if any bass from this connection. This low level output is designed to be connected to another amplifier or receiver with full-range speakers. If you need to connect a second subwoofer amplifier, simply use a “y adaptor” before the inputs to provide multiple low-level signals. • How are the high level inputs used? The high level inputs are generally used in stereo systems having small speakers that product little or inadequate bass. The speaker wire from the receiver connects to the input binding posts, left and right channels. The subamp takes its signal through a 1Kohm resistor on each channel and sums the two. The high level output is then connected to the full-range speakers and has a shallow highpass crossover at roughly 150 Hz. The lowpass active filter on the subamp will generally
