One Last ? About Wire!

my amp is a 1600 rms at 1 ohm hifonics brutus. Its gonna be wired to a MTX T9515, currently i have 4 gauge to a block, then 8 to each amp (Speaker and Sub), i wanna give the sub bigger wire, so

Can i just keep my 4 gauge and run that directly to the sub amp, or should i run 0 gauge and then split it to 4 gauge to the sub amp.??? Do I need to run 0 gauge if the sub will only get 4 gauge is what im saying????

I would reccommend it, yes. 4 gauge can handle whatever current x amount of feet of 4 gauge can handle. Running the sub amp with the 4 gauge wouldn't be bad per se, but it would not be effective or efficient as 0-4/8.

1/0

my vote goes to giving the sub amp a 4 awg wire and the main power wire 1/0 gauge. in theory, you could get away with keeping the main wire 4 awg depending on your gain settings.

there is a table on current and wiring. I still had this in my paste buffer from someone else that hasn't read that site.
