Younger brother of the LM3886 - LM2876 in parallel

Well I for sure don’t need to ask such simple matters so maybe you should follow your own advice. Copy the circuit. Connect inputs to eachother before resistors. Put 0.1 Ohm 5W resistors at each ICs output and join them at the loudspeaker outputs.

It is wise to use very low tolerance resistors when using the ICs in parallel.
These will do the job 5w 0.12r

You can use 0.12 Ohm 5W but I advise to use 0.1 Ohm 5W 1% tolerance. And the other resistors even 0.1% like in the datasheet/evaluation board schematics. Now you tell me why that is.

Do not use stuff you happen to have but use the correct stuff for the job. Better approach if you like success.

High tolerance. Low tolerance means low precision. Perhaps use the phrase "tight tolerance" if you want to be clear. Or even better state the tolerance as a number!!

You asked and got the answers. What you think is enough for you (instead of the IC) may result in either success or failure. Whatever you will use they should be 1% or lower. Do you know why?

0.1 Ohm 5W

Then why abandon the project, instead try hard to get some good resistors. Mouser, digikey, RS components, Reichelt, you have many source. Or take help from forum members or look at Members market, Vendors market etc. It's not a rare item, good resistors are pretty much available everywhere & i think EU isn't an exception.
