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.
