Disadvantages of 0 awg Wire

[AlwaysFollowed 10+ year member]

Hey guys, i just picked up a 1/0 awg wiring kit for my truck. Right now ill be running a single Premier PRS-D2000T with 2 10's from it but will most likely be adding another amp for my speakers in the future. It is 1/0 to distro blocks where it then goes to 4 awg to my amp. Is there any disadvantages to running thick wire such as this or is it the bigger the better? I tried a search but didn't come up with much. Thanks.

nope no disadvantages jus takes up more room lol

So it doesnt create more resistance or some of the stuff ive heard?

the bigger the wire the less resistance it has.

It costs more, and being bigger is more a pain to hide.

That's it.

the "more resistance from bigger wire" issue has to do with the use of single-wire (solid core) wire in applications where high frequency currents are common (eg, in switchmode power supplies). In such cases, the current begins to flow near the surface of the wire, in which case it would be better to use multiple smaller wires.

(solid core wire has less resistance -- there is no air between strands)

the 0g wire in use in car audio systems is a twisted bundle of fine wires. It is flexible and good.

one issue is that, if you have smaller wire elsewhere, the user may choose the fuse size based on the 0g wire, when a fault on the 4g wire might not draw sufficient current to damage the main fuse.

It's not big enough.

Just make sure you have enough power going through. As I recall, if you run like 0 gauge for a 12v application.. results may be a little less than what your hoping for. For car audio, its fine if its a powerful setup.

If it's not fused, and it manages to get shorted out, there will be a hell of a melt down.

Could you explain your statement to me as to why it has to have enough power going through.

Yeah lol??? Basic electronics: Wire size increase than the resistance goes down, Wire size decrease and the resistance goes up. "Just make sure you have enough power" what does that have to do with anything? Are you saying that you need the resistance from higher gauge wires or your current will be too high? //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

Thanks guys, in goes the 1/0 guage today.
