Ideal for a subwoofer or a pair of speakers.
This small amplifier is ideal for a modest in-wall / in-ceiling subwoofer. You can also power a pair of speakers with this amplifier.
You can use this as a stand alone unit, connected to a simple pair of speakers, and use a Smartphone, iPad or other music source. An inexpensive 3.5mm (headphone connector) to RCA cable is all you need.
