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

Sam Kapasi · 13th July 2006, 00:17

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).

SAm... Will help if you could also mention the appropriate GUAGE in lieu of the mmsq figure

low_bass_makker · 13th July 2006, 00:50

some thing from my side

and i will not at all comment on how to calculate the power required by a amp this time now......lol

Can someone edit the pics above to fit on my 12" laptop screen.

low_bass_makker · 13th July 2006, 22:45

here we go man...
LBM edited the pics above. I am leaving this post as an acknowledgement for his efforts but move his pics to Sam's post (post 1) above. - Navin, July 14, 2006.

I'm gonna edit Sam's post with LBM new pics and edit LBM's post accordingly then make this a sticky.

speedzak · 14th July 2006, 13:54

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.

navin ji please edit my 3rd post as i have made a new chart of the awg to mm sizes.....
...chart moved to post 3 as requested - Navin

Excellent one!

Since we are talking about power ratings here I'll add link that explains what amplifer ratings mean here.

something related to wire .........

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.

santosh.s · 18th August 2006, 20:14

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.
