Rear Speakers - looking solutions for low volume

[mister_johnn]

Hi,

I took the car for a drive this weekends and my friends were at the back, and noticed that there's almost no sound coming from the speakers R+L mostly coming from the front. Tried different settings, changed balance towards the back and still nothing... after doing a bit of research I found out that this is "normal" design... more details in the next link:

https://www.clublexus.com/forums/es-7th-gen-2019-present/901662-2019-lexus-es-300h-rear-speaker-problem-13.html

While reading this forum noticed that someone posted that they've had a unit replaced (PN 86280-06232) and that made a bit of a difference #171 

I have some questions:

- did anyone replaced this unit in the UK under warranty?

- what about replacing the speaker with a bigger one?

- can a speaker from the front fit in that space (rear speaker)? I know that the size is different, but maybe there's a way to fit a bigger one

- will the amp have enough power for a bigger speaker? Maybe is limited by software... Not sure.

- any other possible solutions to have a more even and balanced sound in the car?

Thank you!

If it functions this way by design, why would Lexus replace the unit under warranty?

Bigger speaker doesn't equate to louder sound, it has to be driven by the amplifier.

The possible only solution would be to replace the existing amplifier with an after-market offering but IMHO you would kill any resale value on such a new car.

Just asking in case had this done in the UK. In the other forum someone specified that the unit was replaced by Lexus and it made a difference.

Checked now the speakers and a bigger speaker won't fit, maybe a better one of the same size which has also base. I'll need to do more research.
