For many years people have been using passive LOCs to adapt speaker level signals to RCA signals so they can add amplifiers to their systems. The results have been less than satisfactory. In fact many (if not most) folks out there have come to accept the fact that the factory stereo signals are just not good enough to be adapted into a top quality sound system. But they are wrong! Passive LOCs: There is nothing wrong with the factory stereo signal. The problem is those passive LOCs.  Passive LOCs use resistors, inductors, and capacitors to block the high level signal and use up some of the power so it comes out at a lower level. In doing this they add both distortion and noise, and they remove bass information from the signal. This means that the signal coming out of the passive LOC is worse than the signal going in. It has more distortion, more noise, and the low bass information has been removed.  So, when you put this signal into an amplifier you get bad sound made loud. Think abou
