Amp power wire

no, 700 watts would not draw over 100 amps..

at 12.8 volts it would take about 54.6875 amps like bberman said.

i agree that 4 ga is more suitable, as the 8 ga may cause your amps to run a bit warmer than you would want them too, depending of course, how much actual continuous current you would be drawing

if you want to get away cheap, just add another 8gauge power wire for the amp you're adding and remember to fuse it at the battery and a 50 amp fuse should be enough for each amp.

go at least 4awg if not 1/0 awg.

1/0ga for his set up would be rediculious. 2 ga wire for that set up would just be wasting money.

u have a DVC sub woofer which means it has 2 voice coils and depending on the rms of ur sub 1/2 that and thats how many watts each coil will take there are actually 3 ways of wireing these as ive heard u can run them parrallel/series or if u got some money or something u could buy 2 amps and run each to each coil one of my friends does the last one and his s**t is hard so and u can either goto the jl audio site or the audio bahn site to see how each of the other 2 setups would make ur subs react and it all depends on what kinda they are if they are 2 or 4 ohm DVC this is just from wut ive learned in the past 2mnths so ne1 else care to expand or correct me go for it

that third setup you recomended is discouraged by all companies i believe it sends a seperate signal to the coils and if somethings disrupts one of the signals the voice coils are out of sync and basically destroy each other

yea but im assuming the way u could do it if it will work is to hook 1 rca up to each ie red 2 1 amp and white 2 the other ill ask my friend how he does it tom cuz he hooks all of his stuff like that his bro did it for him and he installs stuff all the time

there is jl's dislike for the set up

scorche 4 gauge kit from walmart. cheap and its pretty good.

I got the dual amp set up, so its 4 guage to 8 guage. but for like 30$ you get everythin you need.

Ok here is the set up:

Legacy Red Series 2   ,   1200Wx2,    Model# LA2070

And 2  Volfenhag 15" DVC Subs,  1200W Max, 4 ohm + 4ohm,  Model #ZX-4715DVX

Im putting it in a 2001 Ford Escape, Im going to build the box tomorrow and needed some advice. I'll read the above info tonight about DVC and hopefully ill understand it more.  Thanx Guys

Assuming the Legacy amp  can be bridged, and 2400 watts seems a little much, maybe if struck by lightning. The subs are dual 4 ohm, why not series parallel them and bridge the amp that way the amp will see a 4 ohm load and should not shut down.

Let me know if you need help on wiring the subs.

You have 2 ways you can wire the subs to the amps, either way you will get the same power and performance. 1st way and probably easiest, wire each sub in parallel to its own channel on the amp (top diagram). So you will have to do this twice once to hook up one sub to a channel on the amp and then again to hook up the other  https://www.audiobahninc.com/tech/wiring/parallel_parallel_dual_4.pdf

2nd way and a little more complicated, wire your subs in Series-Parallel and then bridge them to one channel on the amp (2nd diagram down) https://www.audiobahninc.com/tech/wiring/parallel_series_dual_4_ohm.pdf Now your amp should have a diagram on it which will show you a diagram of how to wire the bridge. But normally it will look something like my drawing below. So since you wired your subs together you should have 1 main cable, you will hook that cables + to the plus on the amps bridge and you will hook up the - to - on the bridge 

These are your speaker terminals
