I would go with RF 3sixty-1 or 3 sixty.2 systems., that will give you 3 stereo channels of clean preamp outputs.

You need to connect the line out converter to the output side of the amplifier. You probably need to use a Pac-audio.com sni-35

The reason why you probably can't control the volume, is because they are controlled internally by the levinson amp, i am having the same problem, but i will try to bypass the stock volume knob, i'll keep posting 'till i solve this.

Well, we finally have volume control from the head unit, we hardwired the 3sixty processor's volume control, and left the RF software control at main, no subwoofer control though, but i have 6 channels of clear sound, now on to speaker changing, going with punch components for doors, and trying to fit an elemnetal design eu 700 6.5 woofer
