[QUOTE="clickclickw00t, post: 7925419, member: 644171"] One of the car audio concepts that I got wrong when I first started learning was assuming that your car battery and alternator puts out unlimited power. This is not like plugging a 3000W amp into your house and it draws 3000Watts. In a car, you are limited to the voltage of your battery and how quickly your alternator can recharge that voltage. As the amplifier draws power from your battery, the battery's voltage drops and therefore the amplifier produces less power. Your alternator charges the battery. If you are draining power faster than you can recharge it, you aren't going to get rated power from your amplifier or your subwoofers, and so that $400 sub and that $1000 amplifier will perform like a $100 sub and a $300 amplifier. Some amplifiers are made to put out rated power at 16V, some at 14, some at 12V. If you buy an amplifier rated at 2000W at 14V, you may get that 2000W during the first few minutes of play, but as the battery's voltage drops you are going to be getting less and less power.
