Amplifier current vrs watts; why is current more important?


Lately when talking to knowledgeable people in the audio industry I’ve been hearing how current delivery is more important than watts in determining weather an amplifier will drive a speaker.
So what exactly is current and how does it effect speaker performance? How can a amplifier rated at 150 watts into 8 ohms vs one rated at 400 watts into 8 ohms be a better match for a hard to drive speaker?

Andy2-you were a little off on your car comparison. Wattage/current is kind of like a car horsepower/torque. Torque is your bottom end power. Torque will get you off the line much faster or when you want to pull away. Some cars could have decent horsepower with low torque and that means its gets off the line slower, no power to pass, and all the horsepower is at a higher rpm. Your Sony/pioneer amps might have a decent wattage rating but no current to drive the lower end or react instantly to high peaks
