[QUOTE="enzowho, post: 2709949, member: 568136"] Copper wire has some inherent resistance. This resistance is based upon (among other factors) the wire's length. So, when you run a super long ground cable you have a voltage drop across your ground wire. This means your amplifier/components don't actually set at zero volts. So, if you run a short ground wire for your H/U and a long wire for your amps there will be a systematic offset induced on your components. When you have a voltage offset like this, it allows noise to be induced in your system. So, by reducing your ground length you will decrease the possibility of this noise being outputted to your speakers. [/QUOTE]
