(sorry for my english, I'm french)

I would like to know what is the best between run a 1/0ga from my bettery to my distribution block in my trunk or a 4ga ?

Maybe I could use 5ft of 1/0ga and buy a gauge adapter and put 4ga for the other part ??

Finaly what i the best if we don't think about the price($) 1/0ga? 4ga? or both?

Thanks for your help

What kind of power are you wanting to run,? I use 4ga for my supply, and satisfies my needs

KnuKonceptz Power / Ground Wire Reducer 0 - 4 Gauge 1/0 | eBay

ive had these good quality from what i could tell, and its a great price.

sorry didn't read this clearly, if you are running over 1000w rms i would say get the 1/0, and make sure that you do the big 3 and also use the 1/0 as your ground because just as much power runs through your ground as your power.

im running a 600rms RF amp and a 90.4 high amp on 4gauge wire with stock electrical. And it gives the amps plenty of power, also in a short truck //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Depends how much power you're running and how long the run is. Over 1500wRms, you need 1/0. Under 1000wRms, 4 gauge. in between is a grey area.

Woaw that isnt problem with your wire man... You need to do the big 3 with 1/0 and check your grounds.... What are you running?
