Default So.... why do we need those thick wires??










Thanks to Tobias Runge for provoiding the info and pics to Sam and TBHP's low_bass_makker for reducing the size so that it does not require horizontal scrolling on most computers. (edited by Navin on July 14th 2006).

Great effort from Sam (& LBM) once again. Should be made a sticky as this information will help everybody who needs to do some serious install.

Thanx NavinJi.

A modern 12V amplifier is a current hungry beast. Resistance only makes it mad. Feed it with oversized power cables and you will be rewarded with sonic purity.

While "power" cable needs to be 20 times thicker in car as compared to home audio systems with similar power ratings, the "speaker" cable requirement should not change much. Because for power supply the voltage is reducing by 20 times, but for speakers both home and car speakers commonly have similar nominal impedance ratings. The most common range is 2-8 ohm. What I am trying to say is that to produce a given amount of power from a given speaker, actual voltage/current requirement (which is fed by AMP to speaker) is going to be same, irrespective of whether the AMP is powered by 12V or 220V.
