Is it normal for battery voltage to drop this much?

[QUOTE="Josh Dubin, post: 8667907, member: 676446"] Well I've measured the voltage at the battery terminals and at my amp, with and without music, with the car on and off. With the car on, no music, voltage at battery terminals is about 14V. Once I start playing loud music, voltage drops to as low as low 12's, at battery terminals. Is this type of drop normal, or is there an issue? And would this issue be the alternator ? [/QUOTE]
