Calculating the Total Power Requirement
To calculate the total power requirement of your 6-speaker setup, you’ll need to know the power handling capacity of each speaker. Let’s assume that each speaker has a power handling capacity of 100 watts. To calculate the total power requirement, you can use the following formula:
Total Power Requirement = Number of Speakers x Power Handling Capacity per Speaker
Total Power Requirement = 6 x 100 watts
Total Power Requirement = 600 watts
Since you want to choose an amplifier that can deliver at least 1.5 to 2 times the power handling capacity of your speakers, you’ll need to multiply the total power requirement by 1.5 or 2.
Minimum Amplifier Power Requirement = Total Power Requirement x 1.5
Minimum Amplifier Power Requirement = 600 watts x 1.5
Minimum Amplifier Power Requirement = 900 watts
Maximum Amplifier Power Requirement = Total Power Requirement x 2
Maximum Amplifier Power Requirement = 600 watts x 2
Maximum Amplifier Power Requirement = 1200 watts
