This one. I just ordered the kit for a Mercedes amg gt3 to make a copy of a livery i use in assetto corsa inspired by my personal itasha car. THAT ONE I'm looking forward to
Didn't have any problems with the 3W 4 Ohm speaker i use. It's exactly like this one
It was half inspired by the ETC chimes, mostly it came from the urge to have one of those voice boxes like Waifu Prison or Ressha Melody Box.
It plays a sound file on ACC because i hardwired it to the 12V socket fuse.
I used a 3W 4 ohm speaker and hid it behind that free box under the head unit, and punched holes where its hot glued to.
It needs your head to wrap around some wiring to set these up but if you can get a sound player module like this one you're 1/4 way done.
Just scratch from shapes. I used a program that lets you put an transparent image over my screen that apparently is taken down. There's an archive link here it looks like, https://alternativeto.net/software/image-overlay-utility/about/ in the top comment.
But yeah, lots of shapes, lots of time.

There's a bunch on Amazon fyi

and a hardwire kit so it's 24/7 battery powered.
The cops i talked to recommended a BlackVue because they have LTE and phone alerts, but they're like $700
I bought one of these You can solder a jumper where the button was and then plug a usb into it and it will make the sound on power up.
