THERMAL AND POWER INPUT DATA
INPUT POWER
Generally accepted power levels for thermal and power consumption calculations are 1/8W power input into the
expected subwoofer impedance. 1/8 power approximates usage with little or no clipping of the amplifier and
distortion free operation. 1/3 power equates to severe amp clipping and audible distortion.
