I had just bought this amp time to experiment and then I came up with the idea of a passive subwoofer, the standing around here still unused to make an active. He receives power from a power supply with 12 volts and 5A (2.5 mm DC jack, the signal from a Y-RCA subwoofer cable from the subwoofer output of the receiver to the two RCA audio inputs on the amplifier. For passive speaker input When it comes with a supplied cable that comes by means of a four-pole, square connector into the amplifier, the 4 cable ends (red / black) to come into the pits. turn down treble, turn up the bass and adjust volume level. hifi purists will certainly lack of phase matching and missing setting for Übergansfreqzenz sneer, but it's very good !!! The photo of the back of the "activated" subwoofer looks a bit after 'its self-made bomb. But from the front we see nothing.
If the amplifier is not in the short term gives up the ghost, I give 5 stars.
