We had the same problem as many of you did. The rear speaker in our 2000 Avalon deteriorated. You have to remember that this speaker is part of the JBL sound system for this automobile. The JBL sub-woofer is very low wattage. Replacing it with another speaker, at 200 watts, as some of you have done is not a good idea. Why, because you would need an amplifier to properly drive a 200 watt speaker. Just because a 200 watt speaker works, does not mean it is correct. You can purchase the JBL speaker at a cost of $250.00 from your Toyota dealer, which makes him very happy. I could have purchased it from Toyota for $188.00 because I have a shop and we buy from our local dealer. This particular JBL speaker is only made for these Toyota vehicles and can not be found elsewhere. But, what I found is that these speakers can be repaired very inexpensively. There are many companies spread across the country that recone and refoam speakers, both autmotive and home speakers. Some of these businesses even sell the reconing and refoaming kits, that you can install yourself. I choose to have a company, Simply Speakers (
Official Speaker Repair Page - Simply Speakers - Parts and Speaker Repair) repair mine. Total cost for the repair will be about $50.00.I sent it there, they called me upon its arrival, give me a quote, which I approved, and it should be back in a few days. I will let you know how it came out. Go to Google or whatever search you use, and look up speaker repair. Call them or e mail and see which one you are happy with.
