how thick of wire do i use for my subs

I have a 1500 d and two rf he what gauge wire should i use to power the subs from the amp. The amp puts out 425 watts @ 4 omh per channel.

12-14awg

if you ever plan to upgrade, ever, go with 8 or 4...wire is fairly cheap so why not

subs to amp, not battery to amp

dotn mean to change the thread but while its on the topic about how much power will 4 guage work with befor eyou need to upgrade to 2/1/0 ga.? the reason im curious is the hifonics brutus 1500 had connections for 4 ga. power/gnd wires. is 1500 fine with 4 guage wire? or if not what is the cutoff for about how much power can be run through 4 ga. wire.

oh and i knwo the length of the wire makes a difference but im just trying to get an estimate.. like figure the wire is like 15 ft.

it's based on current, not power

4awg is good up to ~125amps

Yea brutus is fine off of 4 awg it draws <120 amps..... and gluck gettin 1500 out of it....more like 1100 tops.
