The 4.7 Ohm resistors and 0.1uF capacitors are intended to bring stability to your amplifier. Apparently your amplifier is oscillating at a rather high frequency and a lot of current is flowing in the 4.7 Ohm resistors.
You may try with 1uF ceramic capacitors having very short leads and connecting each of the two TDA7265 power pins to ground. Insufficient high frequency decoupling of the power supply lines may cause oscillation.
Else, your feedback layout may be the culprit. Again, use short leads to connect the IC pins.

The paths for R1 and R3 should be as short as possible or you can get instability.
The decoupling should be as close to chip as possible.

Thank you faux French I used 1uf capacitors now its work good thank you once again ����
