which makes more power 4 feet of 4 gauge wire or 18 feet of 2 gauge wire?

 

Niether makes more (or any) power, but I think the answer you're looking for is that you can run a hell of a lot more juice through the shorter, thicker wire.

A shorter or thicker wire will always be capable of handling more power than a longer wire of the same gauge, or a smaller wire of equal length.

Also, when you fuse that power wire (and you'd better), you determine the size of the fuse based on the length and gauge of the wire, not for what's connected to either end.

If you're choosing power wire for your amplifier, 4AWG is a good place to start. I wouldn't go any lower (lower = smaller = higher gauge number) unless you're not running a subwoofer.

Hope that helps.

*edit: If you're going to buy wire, this is the only place worth considering:

assuming the 4ft run would be from a battery in the trunk and an 18ft run would be from battery under hood? You will be better with the 4ft than the 18ft.

 

thanks a lot man this helped a lot

i messaged you something but this clears it all up.

 

yup the battery is going in the trunk

 

2 AWG is an uncommon size also; I know wire is expensive.

Sounds to me like what you need is to connect your battery, now in the back, to the positive terminal clamp under the hood that used to connet to the battery up front.

Make a safe wire and fuse choice, it's worth the few extra bucks compared to the cost of a charred evo.

You don't need to run a cable for the negative pole of the battery up front -- you can just connect it to a place on the chassis with a nice low resistance (use your digital multimeter) and do the same up front in the engine bay with the pre-existing negative terminal clamp.

Sorry if that's a jumble

http://www.weldingsupply.com is a good deal for really big cable, but make sure you pick a high strand count. Current travels on the surface of a conductor, not inside it.

 

x2, just go for the 1/0 awg I ran multiple runs of 4/0 through my car

 

Custel; Didja see the guy at finals 06 running the railroad cable, MCM4 or whatever?

Got one of these comin' off his alt rack:


hehehehe. Stuff's good for 24kV. Jeeeeeeeeeze.

 

LMAO!!! I missed 06 was at 05, damn I wish I could've seen that hahaha. That's just insane....

 

Here are some pics, Custel
