when power wire is too big?

Well, not all of us can be OG CA.com members who apparently look and read much more than they post!

It's been nice, though, here of late to see as many of the original crew (from long before I showed up to be sure) starting to come back around.

Some of you lot are really on the ball!

Screw wire reducers. You lose conducting area with reducers if you are concerned about that... I don't think it would matter anyways. Just trim the wires like most have said. The whole point of having 1/0 wire is to carry the current over such a long length.

The trimmed section of wire is INSIDE the terminal effectively increasing the conducting area to the size of the terminal. It doesn't matter anyway because the difference between the resistance of .1" of 4ga and .1" of 1/0 is below measurable limits. Quit getting wrapped up in queep.

Ummm, no.



What causes the loss? How about resistance? Less resistance means less loss. More resistance means more loss.

Wrong.

I'll just say that I do read alot more than I post. But it's not necessary to defend myself at this moment.

But i shall say that my post is from what I learned in my electrical classes that I currently take. The professor asked the question and I gave the answer that bigger wire had less resistance. He simply stated to me that, my answer was wrong and began to explain to me as to why it is wrong.

Aperantly what I stated only applies to higher frequency A.C. Whereas the signal increases the current tends to flow along only the outer rim of the wire. Thusly smaller wires are better conductors than bigger ones in that application.

I know my bit of car audio. And I'm no noob/beginner. I was just under the assumption that AC and DC behaved similarly in this application.

drop the class - your instructor's a douchebag

I edited a little more of my post to further state what I meant.

There just seemed to be a misunderstanding between he and I

Umm, resistance doesn't apply to AC, it applies to DC ... Impedance applies to AC ... Therefore, your teacher is a moron ...

I'm seeing that he is. I figured that he was an idiot after i said it to him. But, he acted as if I was infact an idiot. So, I assumed that he was correct. Seeing as though he was the professor and I was the student.

Ah well, things happen

It happens...

I know I have had a few teachers that had almost no idea of whatever it was they were trying to teach.

Skin effect is a high freq AC phenomena, not a factor in anything related to car audio.

how about, use the proper size wire... if the biggest wire the amp will except is 4g, use 4g

And if I do, Im sure you'll be around to point it out a day later and several posts after its already settled. It was pointed out to me, I acknowledged it, yet you seemed to feel the need to explain it to me again. Does pointing out the obvious make you feel smart? Nice job.
If you want to ride my balls, at least be original. Im sure I give plenty of ammunition for a guy of your intellect. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
