some of you guys are way off in your reccomendations. First off, if this is only going to be a daily driver i can't see you needing any more than 150a alt and a pair of batts (i have a similar setup). If you are playing music there is no need to have an alt big enough for the max draw of the amps, the person who reccomended 300a was WAY off.
Honestly, i say 1/0awg to a distro block in the trunk, 4awg to the amps from there (remember distance matters more than thickness), and just run a couple batts, one in the trunk one under the hood. I think you will find that it will be good for what you want to run, and IF by some chance you end up killing the alt replace it at that time, you still wouldn't have lost any money.
also remember an H.O. alt generally wont do you too much good unless you are running at 3,000rmp or greater all the time, the output at low rpms is prettly low.
