10ohm resistor and 33nF? should be fine? the RC time constant comes to 482.2KHz
is that value of capacitor ok? Im using two pole compensation in the amp.

Typical values would be 10 Ohms and 0.1uF. However, this depends on the speaker used as well. The capacitor may end up significantly larger than might be expected. This also means that the resistor may have to be of higher power rating than is typically used. A good article:
IC Audio Power Amplifiers and Zobel Networks: One Size Does Not Fit All | EE Times
I didn't like it much - the real threat to most amplifier's stability is cable C load which wasn't included
then you see the need for a isolating series L
others mention L ringing V overshoot - but speaker+cable load aren't a thereat where the Zobel is effective - the bass driver resonance, some XO resonances would be the bigger problem well down in the audio frequency range where the Zobel is useless - use clamp diodes to the rails
