So I've been looking for another alternative, I want something cheaper and ready to ship asap which rules out the BlueBus. Has anyone used these before?

I am linking to this website which charges $75, because it has a lot more detail. However if you google you can find them on Aliexpress or even Walmart for $12-16 and they appear to be identical. E.g. here is the Walmart one I just bought:

Apparently it installs in the back of the Business CD player. I can't really find much more detail than that and I am not sure if it works with DSP or not, if it installs in the trunk or behind the CD player, etc.
Anyone have experience with these or have a hunch? The reddit comment which led me down this rabbit hole says he pulled his CD player and installed it there.
edit: for reference, my car is a 2008 3.0si without DSP or Nav.
