what the heck is this?
 

and don't say"well, it's a subwoofer"

it is a subwoofer, however it looks like one of them ones from the 80's that was a home audio woofer!! 8ohm!! I had a set in my house, sounded alright...

It's a "semi" clear polypropylene cone subwoofer

good? bad? not suited for a car? brand?

Well, taking it out and reading whats on the back of the speaker would help...

Radio Shack sold a LOT of woofers like that back in the 80s

it's a woofer, not a subwoofer. I have a pair of those with some horns at my cabin up north. Freq response of 45-2200hz. has a 1.5" voice coil with short windings to keep unductance low for extended freq response. Suitable as a car sub?... not really. It will move air and thus produce sound...but totally wrong type of application

k..thank you just sar it on a local used site for cheap and wanted to know what it was....some people in this town don't know what they have and get rid of it cheap..that's where I like to swoop in....just scored 2 10's in a box for insanely cheap.

That made me sound like an a-hole didn't it?

Made you sound more like a missinformed hic that is looking to shop based on brand name and pricing with no clue whatsoever as to what he's actually buying....if you wanted to know what you sounded like
