Wvtech's link2 line output converter can produce up to 10 volts of output — plenty enough for your aftermarket gear to work with. Works with factory amps too Those speaker-level inputs can handle up to 40 volts, the equivalent of 400 watts, so you can use one in a premium system with a factory amplifier. This way, you retain all your vehicle's factory audio options and warnings. The link2's gain control and clip light help you keep the signal level under control and distortion-free.
