2 vs 1/0 gauge

[mattmcss 10+ year member]

Well right now i have 4 gauge running back to a D block that has two 8 outs , I'm going to need an upgrade i think ,

I have a concept 1200.1 coming and a concept 100x2 coming soon. So anywyere between 1200-1300 RMS.

Should i upgrade to 2 or 1/0 gauge ? i dont want anything thats overkill that i dont need, should i run 2 gauge to a Dblock and than two 4 outs from there?

2.3 What is the best power wire to use? [JSC]

================================================

There is much debate over the benefit of certain wiring schemes

(oxygen-free, multistranded, braided, twisted, air core, you name it).

However, most people do agree that the most important factor in

selecting power wire is to use the proper size. Wire is generally

rated in size by American Wire Gauge, abbreviated AWG, or commonly just

"gauge". To determine the correct wire size for your application, you

should first determine the maximum current flow through the cable

(looking at the amplifier's fuse is a relatively simple and conservative

way to do this). Then determine the length of the cable that your will

use, and consult the following chart, taken from the IASCA handbook

(see Section 6.1),

Length of run (in feet)

Current 0-4 4-7 7-10 10-13 13-16 16-19 19-22 22-28

0-20A 14 12 12 10 10 8 8 8

20-35A 12 10 8 8 6 6 6 4

35-50A 10 8 8 6 6 4 4 4

50-65A 8 8 6 4 4 4 4 2

65-85A 6 6 4 4 2 2 2 0

85-105A 6 6 4 2 2 2 2 0

105-125A 4 4 4 2 2 0 0 0

125-150A 2 2 2 2 0 0 0 00

If aluminum wire is used instead of copper wire, the next larger size

(smaller number) should be used. You should also consider the

installation demands: will you need to run the wire around corners or

through doors or into the engine compartment? These sorts of problems

in the car audio application require some special care in cable

selection. You will want to have cable that is flexible; it should

have thick insulation as well, and not melt at low temperatures. You

don't want to install wire that is rigid and prone to cracks and cuts,

or else the results could literally be explosive.
