4 guage for 3500 watts?

[danpenksa 10+ year member]

I'm currently runnin 1/0 guage from battery to a distro block in the car cabin (about 5ft)...Then, I'm running 4 guage from distro block to a distro block in the trunk--this is a run of about 10 feet...From there, I am running 4 4 guage runs to 3 jl 300/2 amps and a Stetsom 2k6 amp...

For numerous reasons (fit, having to take car back apart, cost) I would much prefer to be able to keep this longer run of 4 guage to the trunk. Is there a problem with this, considering the amps I am powering...I know it's probably "better" to run 1 guage from battery to trunk and break off into 4 guage runs to the amps from back there, but is my current setup sufficient?

THANKS!

Go to http://www.bcae1.com/ Then go to the wire section and enter your runs and sizes of everything into the calculator.

Wow, do you have any issues with voltage drop?

If I were you I'd run 1 or 2 runs of 0 to a back battery then 0 to the stetsom... 0 to distros for the JL's

IMO the 10 foot piece of 4 AWG then splitting THAT into 4 is the problem.

Thats a lot of current to pull through that one piece of 4 AWG.. even with 10 feet

use 4ga if you like fire //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You should use multiple runs of 1/0 or a single 2/0.

Single 1/0 isn't enough for your set up let alone reducing power with the 4ga to each amp especially the 2k6d.

Thanks for all the input...I will be making many changed to the wiring so that it's done properly

Speaking of, is there a chart somewhere that tells you at what wattage you should upgrade to the next biggest cable?
