Right now i have quality wiring running throughout my car. Its not actual car stereo wire, but what it is is HIGHER grade 4 guage wire that is designed to withstand higher temperatures at a longer time than car wire, thats why it also cost much more money

Well im upgrading from a basic 500 watt rms amp that goes to 3 subs at a 2.67 ohm load

to a..

1200 watt rms amp to 3 subs at a 2.67 ohm level.

Do i Have to upgrade to a bigger alternator, battery, and wiring?

Can i go without any of this because i already have quality wiring?

What is the bare minimum i can do?

PLEASE HELP!!! :)

( The vehicle is a 2005 Ford Escape XLS 2.3L 4cyl.)

Thanks Again.

The wire doesn't matter... It's the load being placed on your alternator, PERIOD.

An additional 1200 watt amplifier (if digital, this will be the best case scenario, if class A/B, the numbers will be HIGHER) will be another 92A worth of load that the alternator has to supply current for, and I expect that that alternator ISNT more than about 65A as it is!

Upgrade your alternator... which necessarily means an upgrade to the Big 3 as well.

Just curious as to what wire you have running where that is better than car wire for a car application. Did you capture a downed alien spacecraft and steal it's technology? Where can I get some?

Funny, but the stuff DOES exist... A good quality, flexible welding cable is a place to start looking for such a specified cable. Teflon insulation, rope lays, mega-multi strands... they all exist. As far as I am concerned, in the car all you are REALLY worried about should be temperature and chemical resistance, first and foremost. Multiple strands are a good place to look next, as the car (being a place frought with vibration) will be quite a bit happier with a nice flexy cable... it'll just lay in place nicer, too. I would finally look for abrasion resistance, although this won't be QUITE as important a spec, certainly. A properly installed power cable should already be routed where there won't be a potential for abrasion.
