If you can afford the optima, get it, I like the idea of high CCA with lightweight battery. I find with a 600+ CCA battery you get good starts, and can play music for leave headlights on for a good 30 minutes without worrying about whether you're going to be able to start the engine or not. the 400 CCA and lower you cant really park up and listen to music without running the engine.

It is true, the alternator provides for all of the the electrical current needs and more when the engine is running.

A capacitor (eg 1 Farad or 2 Farad) will eliminate headlamp dimming, and keep your spark ignition energy high when your subwoofer kicks and also extends their lifespan by eliminating voltage spike/drop.

However I've had to throw mine away as it was slowly draining the battery. If you can find yourself a 100 - 200 AMP relay to enable it with the ignition key, it will be all the problems solved.

Make sure you're running atleast 4GA to your amp
