An audio system of a vehicle includes a total frequencies module that selectively varies a total number of output frequencies based on one or more present operating parameters of the vehicle. An allocation module, based on one or more present operating parameters of the vehicle, determines an allocation indicative of: (i) a first portion of the total number of output frequencies allocated to outputting first predetermined sounds for internal combustion engine operation; and (ii) a second portion of the total number of output frequencies allocated to outputting second predetermined sounds for electric motor operation. Based on the total number and the first and second portions, an audio driver module applies power to speakers of a passenger cabin of the vehicle to: (i) output first predetermined sounds at harmonic frequencies of the internal combustion engine; and (ii) output second predetermined sounds at harmonic frequencies of the electric motor.
