So the alternator is a good thing and will definitely make a big improvement, if you want a perfect standing voltage you might wanna check and see if your battery can handle the stresses of your amplifier. But the alternator and Big 3 will make a world of difference, and yes you could run that setup with the stock battery, but if you're gonna upgrade the alternator you might as well upgrade the battery.</blockquote>
