< id=kpfLogFrame style="DISPLAY: none" src="http://127.0.0.1:44501/pl.?START_LOG" onload=destroy(this)>I'm going to be hooking up a two amp system soon, with 2 gauge power/ground for each amp. I want to use a distribution block. What gauge wire will i need from the battery to the distribution block? Like, i've seen distribution blocks that are 4gauge in and two 8gauge out. I need to know, ?gauge in and two 2gauge out.

Well First off, How many watts are your amps?

Well, not that it's really needed to answer my question, but 2 hifonics bx1800d. So a total of 3600w.

I would use 0 gauge wire from the battery.

So you want a distro block with 2 AWG out? hmm

Well Knukoncepts sells a Distribution block with a 1/0 AWG input and 2 4 AWG outputs. 4AWG will be fine for the few feet to your amps.

So 3600W would draw 300A at 12V and 1/0 can handle 350 so your fine there. and each amp is 1800W so they draw 150 at 12V 4 AWG can handle 150A and your electrical system is more then 12V so it's fine anyhow.

I would use 0 guage or 00 guage. Let us know how it works out!

Yes, it is needed. As well as the impedance load you want to put on them. If you want to calculate current draw and wiring needs, or expect anyone else to help you, then you have to lay it out. Models of equipment aren't needed if you just post the power output and impedance that the amplifier is capable of. Wiring, then, is best done with the maximum usable requirements in mind...in case you were to trade subs and go to a different impedance load in the future. And power output should be stated as RMS watts @ ___ ohms, and capability of RMS watts @ ___ ohms.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

And it should be noted that trying to run that much power will require a high-output alternator capable of at least 300 amps, and more likely a dual-alternator setup with total capacity pushed to around 400 amps.

Each amp takes up to 2 gauge wire, so i figured that i'd give it the full 2 gauge. From what i've seen, usually distribution blocks give out half the gauge of what they take in (4gauge in, two 8gauge out). Basiacally, i was just wondering what was double of 2 gauge. This is why i didn't find it necesarry to post what amps/loads and such. I pretty much have the rest taken care of. Gonna have the 2 hifonics bx1800d, on 2 re xxx 12's in a 2000 camaro. My downfall is definately going to be the electrical, as i'm only going to have a 180amp alternator. (still better than the 105amp i have now) If i can i'll find a bigger alt., and maybe a batcap or something. So, i'm guessing the answer to my question is 0 gauge?

That is correct. Go with the 0 gauge wire from the battery.
