OK, the "true" purpose of a line driver is to raise the carrier voltage of a line level signal.  This is used to increase the signal strength and is generally useful if using long (>25 ft) RCA cable runs, to overcome induced RF or EMI noise, and/or to amplify a weak line level signal from a source unit.  In general, they do not make a system "louder" or "cleaner," but they do enable artificially high amplifier gain in a SPL competition setup or allow use of lower amplifier input sensivity for an SQ setup.  I generally only recomend them if you have to run very long RCA cables for some reason, if your head unit puts out less than 2 volts, or if you're using the OEM head unit for some reason and you need an LOC.  A line driver can actually make some systems sound far worse, as they will amplify whatever noise or distortion the source unit produces and they can overload the input of some amps or processors not designed for their high voltages.Support the12volt.com
