2nd Gen Quick Factory JBL Front Sub Speaker Fix

Purchased Used 2010 double cab a couple of months back with 53K miles. Factory JBL sound system. The front driver's door sub speaker was blown when purchased. Figuring that should be easy, and it is, but sticker shocked at $150 replacement each. I'm not super cheap but there's really not much to this speaker and it should not cost more than $35 retail even with it's custom impedance (ohm value). I pulled the speaker today with a little help from: https://www.youtube.com/watch?v=chR6DiAk5rQ successfully removed speaker and simply held it in hand while listening to blown rattling sound at low volume.


The outer suspension was not compromised like I've seen on Gen 1 tundra forum speakers. https://soundcertified.com/wp-conte...aker-parts-diagram-and-examples-close-up.webp

I put a little finger pressure directly on the cone from back side and the blown rattling sound became less audible. I placed gentle pressure directly on the cone from opposite side at the same time and the speaker then sounded like it should driving lower frequency bass sound. This seemed to indicate inner suspension (spider/voice coil) failure.

I found a piece of medium duty foam in the garage:



Cut (2) 4 finger sized foam blocks and squeezed between speaker chassis and cone shown here:


Put it all back together and now sounds like my speaker is no longer blown, in fact, it sounds way better than it did. Nothing to lose here. I'll keep the fix in play until I can find a reasonable replacement.
