You could also use this amp to power a system consisting of two speakers and a subwoofer. If you're just interested in power, this amp can go into bridged, 2-channel mode and put out up to 150 watts RMS per channel, for a couple of high-performance tower speakers, for example.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eTone controls for the best sound\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eHigh-pass crossover filters guard against low-frequency distortion in your speakers.
