How do I replace the "big 3" (battery to chassis ground, engine block to chassis ground, battery positive to alternator) on a Honda s2000?

My battery keeps dying (not just losing voltage, my replacement batteries die after about a year). It's not the alternator, the alternator charges the battery just fine - it's just that all my batteries start refusing to hold a charge for longer than a day or two. I've tested my resting electrical drain, it's within normal.
My mechanic (and the rest of the internet) is telling me my amp's killing my battery . (My amp is only 800 watts -- I know it sounds big but its a loud car). The most obvious first fix is to replace the "Big 3" with 0 gauge wire, according to the above sources.
The problem is under the hood of the s2000 is a hassle. I can't even find the route the positive wire takes to the alternator. I don't want to take out the engine to do this. I also can't even find the engine block ground. About the only one I can find is the battery-to-chassis ground. *sigh*.
I don't want to pay a mechanic to do this, because it should be easy, and wire, even high-quality 0 gauge wire, is cheap.
