Use a good heatsink for the LM317 IC and adjust the 5K variable resistor so that you have 4.5V on 10Ω resistor (or LM317 pin 2, Vout).

Power amp LM317 Wao Daya 1 Watt
You probably know that LM317 IC is used as an adjustable voltage
regulator, but did you know it can be used as an audio amplifier? This
is a class A audio amplifier built with LM317 that delivers a maximum 1W
audio power.
Use a good heatsink for the LM317 IC and adjust the 5K variable resistor so that you have 4.5V on 10Ω resistor (or LM317 pin 2, Vout).
