Speaker Update for anyone with a first gen Sequoia and possibly applies to Tundra. Factory JBL speakers foam around the cone dry rots over time and the speaker sounds blown. It's not. I popped off the door panels and our foam is intact. The foam delaminated from the plastic housing. Or metal whichever it is. I popped off the top plastic ring and decided since it looked pretty good to hit it with FLEX SEAL and then after that semi cures I will then use Marine GOOP or silicone cauk to re-attach these plastic top rings. I really think this is going to work and not be completely GHETTO AF!
