you should already have a permant live wire in your dash if there has been a previous stereo. if your not sure of the wire colour you can either get a meter and test the wires with ignition off. or if you have a block connection go to a car audio shop for i converter wire- really simple then just plug in an your in business.
as for the earth you can link a wire up to any piece of bare metal behind the dash.

Alpine do recomened a dedicated live for the high powered units.
Simply run a cable straight from the battery through a fuse then to the head unit
It should recommend a cable and fuse size in the manual. 
It will work from the normal stereo power supply - it just a recommendation

alpine recommend it to keep your memory settings not having a live feed, you will have to tune your radio, eq etc everytime you start her up....jay

This is quite right. It's to do with current draw through wires on older cars - modern cars ae fitted with reasonable guage wires that will handle the current draw of high power head units. Older cars (that utilise very thin guage wire) will struggle.

If you are fitting to a mk4 for example, it's unlikely this would be needed.

Take a look at the loom in your motor and make a sensible decision based on that.
