2021 Sienna XSE (non-JBL) Audio Upgrade - Part 1

Taking off some trim panels, looking for wiring on the door speakers.

Hi Aaron, I am about to start the upgrade on my LE. I got the Kicker DSP, ordered the GS690 & GS25s. I just want to ask what happens with the middle row speakers and liftgate speakers? Are they still functional/running parallel with the other outputs?
Are the GS690 paralleled with the GS25?
Thanks

I don't have my Sienna anymore, but from what I recall, the G690 and GS25 should be on seperate channels of that amp, basically you want to run it as a 4 channel amp. You'd just leave the rear/middle speakers attached to the factory headunit connection.

[@joeandjinuscanadiancafe]

How about rear door speakers? Whats the replacement type for those 2?

[@aaronmorris9352]

They're a small one just like the dash, so most 3.5" or 2.5" would fit!

Hello, I would like to know what brand of speakers the 2021 sienna comes from the factory for that XSE model?

[@Aahanahetvikalpesh]

JBL

Do you have a link on how to remove the radio? I can't seem to find one on the web.
Thanks

I believe I have a how-to on the Sienna forums. www.siennachat.com/threads/build-log-upgrading-my-2021-sienna-xse-w-o-jbl-audio.67389/

Why not run new speaker wire?

[@aaronmorris9352]

You could, and in fact later on I just decided to run wire from dash to the amp and then just leave the rest stock. Stock wiring is plenty good enough for under 100W.
