Speaker wiring ?

most speakers come with 16GA or smaller,if your running a amp, youll notice the wire gets a little warm.I usually run 14 GA or bigger anytime i install or sell anything.

Yes it does matter, smaller wire will build up resistance

How much juice are you running to the speakers, amp, or just head unit? I also say 12 gauge or bigger, for speakers with amps running more than 200 watts.

I would run 12 gauge to the 6x9's and the 6 1/2's, and 10 gauge to the sub, you could also run 14-16 gauge to the 4 speakers, but you really need at least a 12 gauge for the sub, so you keep everything nice and cool.

12 guage for anything but a subwoofer is overkill.

Even 14 guage is overkill. 16ga is usually the perfect size..18ga if all you have powering the speakers is the head unit.

You can run a 16 from the head to the amp as the on/off or radio signal wire, and I'd run 12's to the sub since it'll be getting the most juice. 14s are nicer for the 4 satellite speakers, because it'll keep the wiring cooler than 16s, and cooler wiring means less resistance and clearer sound. Of course you can take this too far and go way over the top, in which case it's just plain silly.

How are you splitting up the power? Is it a 600W amp with 4 satellite outs and a seperate sub out, or do you have a seperate amp for the sub? I recommend, to music gurus who can't live without it like myself, having a seperate sub amp if you can afford it, because you can get better control of crossover frequencies and the fine adjestments that can in my opinion make or break a sound system. Also, if you push it too far and blow out the sub amp, you still have your satellites working.
