Anyone install a active sub under 2023 passenger or driver seat?

I did. It adds some depth to the bass, but definitely still a little lacking. I'm happy with it though.

 

after seeing this yt video, i inquired about the 5th gen prius and here's the response.

Honestly, setting aside lack of subwoofer I'm really amazed at just how far stock audio has come.

While not quite as punchy or clean as my amplified 6 speaker kicker KS series speakers I got years ago when I worked at best buy with a wild new dealer price package (it was around 30% MSRP to get us to buy to then sell to folks), the SE prime has great speakers stock to the system all things considered. A future easy integrated small subwoofer would be really cool though.

 

can you list the ones you have learned that fit underneath the front seat? your recommendation? the oemaudioplus solution looks very integrated and i expect it to be priced at a premium.
