If the audio device has a bass tone quality that is less kicking, to overcome this problem is to add an active subwoofer / crossover filter so that the tone other than the low frequency will not be passed to the power amplifier and the sound coming out of the speaker will appear even more. This the figure of the schematic diagram.

This circuit uses the main component IC 741, this IC can be easily found at the electronics component shop store, this IC can also be used as a complement to the temperature sensor circuit and I have used this IC before for the egg incubator circuit.
