Question LM3886 Amplifier help

I am planning to build an amplifier soon.

I need some help with wiring and choosing parts.

here is what I have for the output stage.
resistors are 10 watt.

will it work for a sub-woofer?

Why not use 3watt resistors, 10watts resistors are overkill.

Iím not sure but I think the resistor-capacitor goes right after the output, before the resistor-inductor

Default LM3886

Don't use the 10 ohm resistor and the inductance. It is used for long loudspeaker connection wires. It can ossilate. Simply use the zobel. 0,1 microfarad and a 2,7 Ohm resistance.
