This one gotta buy at SC or parts center, dont think it will be expensive.

BTW, I remember you said wanted to upgrade car audio.
Eyeing Edifier G651A if not mistaken.
Change d? How was it?

Thanks for updates!
With limit bootspace in IRIZ, I supposed you left with limited option.
Underseat woofer is good option thou, but it may not hitting the lowest notes...

Underseat subwoofer normally build in teeny tiny amp.
You just need to find a way to feed power and audio source.
Wire splicing/soldering might be needed.

Btw I installed SF651A, quite an upgrade to stock speaker.
But the tweeter can be better IMO.

yes stock HU.
Bass definitely better than stock, but I feel it can drive harder by better HU or amp.
The only problem here is "strange" soundstage due to tweeter placement different than woofer (opposed to stock full range speaker), it take some time get used to it.
Of course it's not hitting the lowest note, but it's more than enough.

Also, I'm kinda disappointed with the performance of tweeter.
They should include better tweeter at this price.

Does any know where to buy the plastic part on standard variant that used to fit radio control button?
The one look like this.



Reason being I want to fit aftermarket button on my steering nicely but I don't want to tebuk lubang on my original cover.



So the end result (hopefully) look like this.


Picture borrow from shopee.
