[QUOTE="Kyle_Keating, post: 3991737, member: 582385"] amps don't matter, its power or better yet, energy transfer. P=IV relativity speaking, you need both high volts (potential energy) and high amps (amount of charge(electrons) moving per unit of time) to have high power. Think of the electrons as marbles, then roll them down a street that has a slight tilt and let them hit your foot after 100 yards, no big deal. Now drop them 100 yards in the air (high voltage, same current) and let them hit your foot. Big deal! Also, the current, resistance (impedance) and power for that matter are non-linear with respect to frequency so they are change all the time, every split second, the only thing that remains constant is the voltage unless you're playing only 1 frequency... a la burp test? or what-have-you. What really matter is how much voltage you need for your specific subwoofer(s) and how they are wired. Most amps will produce different voltage maximums for different resistive loads. The voltage is called your "gain" which depends on on that setting and your input voltage from your headunit too. [/QUOTE]
