This tool calculates the total power consumption of a set of subwoofers. It also gives the amplifier requirements to drive these speakers.
Enter the wattage of the speakers with each value separated by a comma.
Example Calculation
If you have three 50 W speakers, the total wattage is 150 W. These speakers require an amplifier capable of producing between 135 and 180 Watt.
When looking at the manufacturer’s data sheet specifications, use the RMS power and not peak power.
Can I drive my subwoofers with a lower wattage amplifier?
Yes you can. The downside is that you won’t be able to maximize the performance of the sub. Remember to ensure that the amp is not operating at levels where distortion or clipping can occur. This will reduce the risk of damaging the coils in your subwoofer due to a higher average power.
???? Use this tool to find an amplifier to match your subwoofer
