Replacing MBP late 2016 15" speaker

[M0bi0us0ne]

Opening up my late MBP I messed up the membrane of my left speaker, an authorized Apple repair center quoted me 650 euros to replace the entire top case (the speakers are glued to the body of the MBP).
I managed to find a set of speakers for 70 euros harvested from a dead machine, so it is possible to remove them.
I was wondering if anyone knows what is the best way to soften the adhesive holding the speaker in place? Do I need to use heat? Is it the same glue use for the battery? Do I need to get the battery solvent from ifixit?

Thanks!

Removing it is properly the easy part.
You will need to use a heat source, and properly some isopropyl alcohol to clean up residue. it can also help softening the glue.
The ifixit iOpener (https://www.ifixit.com/Store/Tools/iOpener/IF145-198-4) can be used if you do not want to apply a heat gun, or another source directly to the MBP. A hairdryer would properly do fine. You need to think about how much your heat source spreed, as blowing hot air might warm up the glue in other places too.

what would be the hard part then?

not breaking anything else while doing so
But I can see from the ifixit teardown that you will be able to take almost all hardware out before doing the replacement. so you should be fine if you take your time doing the repair

I'm debating if I should remove the logic board or not

 

[Schranke]

without having looked under the hood in real life (only pictures) I would remove the logic board. this is mainly due to not being sure of how well the speakers is glued on, and how wires and other stuff goes around. also removing the logic board ensures that I would have one less thing to think about. I do have experience with removing logic boards in other MBP models and they tend to be removed easily. Just be aware and carefull disconnecting cables, especially the screen cable.

I removed the logic board once before when I had the ill fated idea of repasting the CPU with liquid metal (don't do it!!!)

Oh, you are a brave man. Have replaced TIM a bunch of times on older MacBooks, and will do it in a years time on my 2017. But I do not have the nerve to use liquid metal. Will be keeping with kryonaut

 

[M0bi0us0ne]

I applied conformal coating around the GPU and CPU but the liquid metal managed to fry a temperature sensor leaving one of the cooling fans constantly spinning at 110%. Thankfully the authorized repair center where I brought it in closed an eye and swapped the logic board under warranty.

wow that was a thing to do by them
