I don't know if anyone has answered the L.O.C. question about why they sound better.

The speaker wires carry enough voltage to power speakers (obviously), where as RCA's are meant to carry lower, crisp, clear voltage between 2-5 volts usually. What a L.O.C. does is it inputs a speaker signal and lowers the voltage to a clear voltage, then you run RCA's to the amp, and then the amplifier brings the voltage back up to a high voltage to power the speaker, PROPERLY.

The problem with soldering RCA's right onto speaker wires, is that the RCA is now carrying high voltage, which was never down graded to a lower voltage, so that amplifier will send out a more distorted, lousy signal, which is why if you're looking for a quality sounding system, spend the extra 50 bucks and just buy a L.O.C., they're easy to wire, figure out you're factory speaker wire colors, and wire like this
