To start, I am a complete noob when it comes to car audio systems. I have a 2009 Toyota Camry SE with OEM speakers I believe. I've only noticed this problem occurring when a certain bass kick sound is played. For example, I've noticed parallels from two different songs by Logic those being Gang Related(@0:29) and Welcome to Forever(@1:07) as well as a couple other of his songs. This I'm assuming is only happening to this one specific frequency and this particular artist likes to use this frequency over and over again. I just want some guidance as to what to do as I have no idea what to do from here to fix this issue. I have noticed that sometimes the sound will restore randomly then it will distort again after some playtime. I do play my music loud but not crazy loud (if that makes sense.) I know it's not my door speakers making the popping noise as when I turn the bass all the way down on my cars EQ it still makes the popping noise at the same volume. When I turn the treble and mids down or up the sound persists. Hopefully I've provided enough information to start troubleshooting further.
