The NVX XFLOC2 Premium line-out converter is the perfect solution for adding an aftermarket amplifier to your stock stereo system. The XFLOC2 uses the signal from your stock stereo or amplifier by tapping into the stock speaker wire and converting it to a 2-channel RCA signal output. This allows you to add an amp simply and effectively. It features a 6:1 Step down with an adjustable gain output, DC amplifier turn-on trigger and a 80 watt maximum input. The XFLOC2 uses a digital noise filter to reduce static and other noises that sometimes occur when adding a line out converter. The end result is a high quality line out converter with super low distortion, and as with all NVX products the engineering and build quality is second-to-none.
