big 3?'s

I'm only running 400rms and was wondering if I could do the big 3 upgrade with 4 gauge wire I got some extra laying around? And if so could I use the 4 gauge if I were to run 800rms?

i would reccomend using 1/0 wire but when it gets down to it if its bigger then what your stock wire is then its gonna be better regardless.

u dont rly need the big 3 for 400 watts but it doesnt hurt, 1/0 is recommended, 4 is prolly better then ur stock so why not if its just laying around
