Apparently this unit plugs in the backs of many Alpine head units, and provides 45RMS output to four channels. This seems like a cheap way to install the amp for all four speakers without any of wiring headaches. Price: about $100 bucks. Has anyone had success with this product in a Taurus? I am only wondering whether the Taurus head unit wiring is good enough to power this thing. I have head at least one reviewer mention that the power cable has to be rated for 15 amps.
