I'm using mine with a Clarion DXZ615 and am pretty pleased. Good input/output options on the Clarion and a good amount of tuning ability. The Clarion is acting as pre-amp connected to my JL Audio amps. In-cabin speakers driven along one pair of connections and subwoofer from another pair. No fade control from the Clarion, but it's nice to be able to adjust input sensitivity as well as non-fader (sub) volume.
