I’m considering upgrading my speakers internal wiring

None taken but I’m curious… did the upgrade of wire enhance the sound in a positive way. I can only speak from my own thoughts and say… if everything matters why would we stop directly before the actual speakers themselves and say that should not matter as much? It’s the final point of contact before our ears

Hey, it can't hurt to contact the OEM and just ask what is worth changing out or replacing internally. Especially if the speakers have some age on them.  Who knows, there maybe some parts that he will say "swap x out for y" because y is a better part that wasn't available when the speakers were made.

But if you do make changes, you will invalidate the warranty (if it is still valid) and if you ever send it back to be fixed, they may refuse to work on them.  And document everything you do, take pictures and keep the old parts.

These are not old. Less than 2 years. I’m not concerned about the warranty as there really is not anything to a speaker other than drivers and crossovers… This is basic and not so much as an experimental experience. lol 

I changed the wiring and the crossovers at the same time.  Noticalbe and excellent changes, but can't say what the impact of the wire was.

Warranty law:  Something breaks, they have to show that what you did caused the problem to deny the claim.  Now if you're clueless and can't argue your side, you'll lose.  but if you can condfidently say that the wire you installed was as good or better and that it was installed properly, you haven't invalidated the warranty.

Now if you put an unapproved racing oil filter on your car and the engine blows, that's not gonna be good.  but if you work on the door handle and the windshield wiper quits working, no relationship.
