2016 Avalon Limited Dash Speakers

I have a 2016 Avalon Limited with the JBL system that is pretty disappointing. For starters, I want to get clearer sound out of the dash speakers which sound dull. I am trying to figure out how to remove the dash speakers. Any help would be appreciated. I have received no replys on the Avalon forum. I guess not many people work on their cars over there. Appreciate your help. (The door panels are very easy to remove but the dash seems to be more involved).

Dash panel needs removing. See the pictures for your model at cruthfield. Toyota dash speaker cover panels usually pop of with normal plastic trim tools

So many trolls so little time

Thanks for the reply. I have used Crutchfield in the past but have noticed that they sometimes leave out an important step when they generalize a procedure resulting in something getting broken. (Ask me how I know)?! The Avalon does not have single speaker covers (that I see) that actually stand out so I am guessing it is more involved. Sure the 'A' pillars have to be removed but guess I will just try and see what I can do without breaking something.

I am beginning to think this is a waste of time because I still have to find a speaker that will drop into the dash that can handle the crap JBL systems 2 ohm impedence. Its like fighting with a Bose system which was pure hell.

The filtering on the JBL system is active meaning done before the amp... there is no passive filters other than maybe caps on the coaxial mounted tweeters. My point is that replacement the speakers with a different impedance (4 ohm) will not effect what frequencies the speaker receives... Though it will likely reduce the amount of power the amp is capable of making (half the power or 3db less). So if you know the efficiency of the factory speakers then just get some 4ohm aftermarket speakers that have at least 3db more efficiency then the factory speakers. This won't be easy as factory speakers are usually more efficient then most aftermarket speakers.

In my experience, it's not worth swapping out just a few speakers in the JBL system as it usually results in less output and worse sound. The JBL amp module has built in signal processing (filtering & equalization) that is engineered specifically for the speakers that are used. Just installing different speakers without bypassing or properly re-engineering the signal with an aftermarket dsp is generally not a good idea and results in wonky performance. As you alluded too - just like factory bose systems.

Yep, we all did (that have it). In 2008 when I bought my Camry I thought the almost $2k cost of the premium JBL system was the smartest thing I could have done. Well...nah. If I had known then the limitations I would have skipped it and put in a high end aftermarket later. It was OK but I have never been super impressed. And back in 2008 the only input was the AUX cable, which sucks. No BT for audio, no USB interface. I've put in a new aftermarket HU and the radio interface kit to deal with the JBL amp, and know I am kind of stuck with the speakers unless I tear it all down and start over. Oh well.
