Speaker Wire to use with 900W RMS to 2 subs

[stevo1988 10+ year member]

I have a mono amp capable of putting out 900W @2ohms to 2 subs (450W to each) and I want to know what gauge for speaker wire i should go, I am only running the speaker wire 3-4 feet or so

17-14 ga should be more then enough

yea.... i would go with 14... maybe even overkill it with twelve.

i WAS gonna use my left over 8ga power LOL overkill for sure, but i dont have any better use for the 8ga...i would too if my box terminals were big enough

ill look for 12ga tho

i used 8 for the hell of it one time ahah

it was for a lil 8 in the rear fill of a lexus

i was only giving it 300 rms hahaha

the amp was about 6 inches from the sub and i had a 40' loom of 8 guage

so i figuerd ehh.. what the hey

yea! really! i wish my terminals were bigger, the 8ga would not only be overkill, but cheaper too! lol

are they push terminals? most push terminals can use 8awg..thats what I would do

yes they are push terminals but they are pretty small...i might have to shave off some strands to get it to fit in

The length of the run has more to do with gauge choice than power does when it comes to speaker wire. Believe it or not, it's true. The is because the longer the wire, the more resistance you'll have. The only reason to use larger gauge wire is to reduce impedance. If the impedance of the wire is more than 5% (10% at max) of the impedance of the speaker, then you will get large changes in frequency response. Here's a chart to help you choose speaker wire:

just strip the wire, trim some off with some snips so it fits

Thats what I did.. I got Metra 4ga as speaker wire.. more like 8ga actually

haha awsome, will do...this stuff is finely stranded so it shudnt be too hard to snip off some and fit it in, saves me from buying 12/14ga wires...just recycling the old power cable (which costed me nothing in the first place)

im running 0 guage power wire to my amp lol
