Determining Your Amplifier Needs
for Sound Systems
Step 1: Fill out Wattage Tap Requirement Chart (to right)
determining the number of speakers that will
be used at each wattage tap for the amplifier.
Step 2: Multiple the number of speakers by each wattage
tap to determine Total Wattage Requirement per
Tap setting (See Ex A).
Step 3: Add all the figures in shaded area to determine
the total Wattage Requirement for the amplifier.
Step 4: Match total Wattage Requirement to the bottom
chart "Recommended Amplifier Wattage Chart"
to determine acceptable RMS Wattage your
amplifier should have.
Step 5: Repeat this process for each amplifier system
required.
