My new wire!

I'm not going to debate the reason for more stands.But... A conductor with many small strands of wire will carry more current than a same size conductor with fewer, larger diameter stands of wire.

Current flows on the surface, doesn't matter if it's a distribution block, terminal, or wire... current still flows just on the surface.

The conductor with many small strands will have quite a bit more surface area if you were to do the math and calculate the surface area of each strand and multiply that by the number of stands.

The larger strand wire, with fewer strands, will have far less total surface area. All of the material of the strand other than surface area does not conduct electricity.

.

yet you did and see what happened. I didn't even bother to reply, at first.

no

Try again. DC vs AC. Very high freq AC flows on the surface. Audio range AC and DC use the whole conductor

Skin effect isn't an issue until you are well outside of the audio bandwidth.

as long as it works fine for my install its ok with me. I'll let you guys know how it comes out. Im replacing 4 awg Stinger with 2/0 welding cable (HUGE difference in physical size). So Im not going up in strand count (maybe even down), but I'll let you guys know how it turns out when i just directly replace the wire without replacing my subs and amp yet.

Well...the ground wire will be the biggest restriction there....Also, since we're on the debate of wiring, (sorry to threadjack)

- Wouldn't the best ground be to wire directly back to the negative of the battery? Aside from twice as much wire being used, is there anything wrong with that? More importantly, is the 100% solid ground worth the cost of extra wire?

Hey! You and I have the same truck! 01 chevy s10! Cool. Lemme be the first fellow minitrucker to welcome you here!

Answered my question. Yes its ok to ground your amplifier at the battery.

Refer to Squeak's post about resistance. If you are running low (numerically high) gauge wire, then the shortest ground is best to maximize the use of the higher grade medium.

Yep, it appears that I'm wrong. I've dealt mostly with AC current (440 3 phase) and RF radio... I'm not sure why I assumed skin effect applied to everything. Anyway, sorry for the bad info, and thanks for the correction. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
