What gauge to use from subs to amp?
Thursday, August 28, 2008 11:23 AM
Alright so I recognize this is probably a stupid question, but to be perfectly honest I do not know the answer.

Now my amp is wired with 4 gauge from the battery to the amp, as well as the ground. HOWEVER I do not know whether or not to wire the sub to the amp (through the box and what not) with 4 gauge wire also. Common sense tells me yes I should, but whenever I argue this with my friends they say "no you just use like 18 gauge or whatever speaker wire".

I just wanted a solid answer once and for all by people who actually know what they're talking about. Also if I'm right and you use 4 gauge in my situation, wouldn't i have trouble getting it to connect to the terminals on the sub? or do I by connectors?

thanks in advance, again sorry if this is a ridiculous question just my friends and I differ on opinions towards this.

well if i read that correct no donot use the 4 gauge to connect the subs to the amp.

and no do not use 18gauge wire. you should use 14 gauge wire that will be good for the subs.

oh ok thanks. I just presumed since your amp needs 4 gauge to get an apropriate amount of power (in my case 750watts) I assumed if you used lower gauge after the amp (i.e. to the subs) that it would kind of be a "bottle-neck" and not all the power would get to the subs.

Thanks again.

I am using 12 ga wire from amp to sub. Amp puts out 1000RMS at 2ohm to 2 alpine type R's. But 14 ga will be fine too

It all depends on how much power you are using... 750 watts, yeah, 14 guage will do ya fine.

meh, i have been using 8 guage but it was already there and easier than hunting down something smaller. would've been interesting trying to run 1/0 though

honestly with as short of a run as that would be 18 ga would probably be fine, however, 14 and 12 ga is not that expensive so no reason to not spend a few extra bucks(literally like $2) on that wire.

i'm using 12 gauge though if you would like some reference

i actually think he has 4 gauge to each of his subs.... his remote wire is 8 gauge and he has like three runs of 0 gauge power wire.
i have 10 gauge from amp to sub and im happy with it

any gauge wire will do.
if your pushing a heavy sub you'll want a smaller gauge to help feed the watts.
8/G is usually the best bet.and will fit most amp speaker terminals.
