*Description*
If your iPhone 17 Pro Max bottom speaker is very quiet, sounds muffled, crackles, distorts, or has no sound at all, this step-by-step guide will show you how to replace the bottom loudspeaker and restore clear audio.
In this HowFixit tutorial, I’ll show you how to safely open the iPhone 17 Pro Max, disconnect the display, remove the cooling plate and Taptic Engine, replace the loudspeaker, test audio performance, and restore water resistance with new adhesive sealing tape.
This repair is useful if your speaker problems started after a drop, water exposure, or internal speaker failure. I also cover important tips like keeping track of screw positions, avoiding damage to display cables, making sure the speaker sits flat to prevent buzzing, and testing sound before final reassembly.
