ok... did some researching in previous threads and want to make sure this is about correct. use 12ga wire for subs and 16 for speakers? thanks

Depends on Watts, Ohm load, and length.

he doesn't need to use 8 awg tho for speaker wire... not gonna do that much good.

who said 8g ?

speakers:

175 watts at 4ohm bridged

subs:

1500 at 2ohms

In the calculator you'd put in the individual ohm of the speaker and if more than one speaker of the same ohm is sharing the same channel, divide the watts by the # of speakers.

So if your 1500wrms @ 2ohm is actually two 4ohm subs getting 750 rms each then enter it as that.

no, im gonna be using 2 subs, each running off of 1500

No -4 Gauge for power and 28 gauge from speakers.

You will be ok with 16 for speakers. For the subs you might want to use 10g to be on the safe side. You're trying to use a wire rated for 21 amps to handle a 27.4 amp load. You might get away with doing so since music is dynamic and impedence rise though.

Not always true. If the subs are wired in parallel, then the wattage per wire is divided by 2. If they are wired in series, then the full current will pass through all wires.

True, I rarely see people doing that so it didn't come to mind //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

use whatever is the cheapest for u. Unless ur running huge amounts of power, u dont need anything big for speaker wire.

Like someone else mentioned, it depends on the amount of current and length of the wire run. If the amp is next to the enclosure then you could get away with 12ga wire, but you'd be better off with 10 or 8 ga wire. I never run anything smaller than 8 ga, but thats just how I do things. The larger the wire, the more wire strands which makes less resistance in the way. You want all the current hitting the subs, so the larger the wire the easier it is for that current to reach the subs.
