This is the BOSS Audio BASS1200. They now make a BASS1500 which looks very similar. It's designed to work as an under seat subwoofer. I have used them in my various subaru's for years with excellent results.
It doesn't appear it will fit under the seat of a sonic without protruding well into the rear footwell but it would easily fit under the rear cargo tray.
I realize haters gotta hate but before you knock this inexpensive subwoofer, I would suggest you have a listen for yourself. It allowed me to lower the bass settings on my head unit allowing me to play music louder and clearer and providing an excellent amount of thump for the money. You can buy one for about $130 shipped from Amazon or ebay.
Excuse the dust, I pulled it straight out of my subaru where it's hidden under the seat.
And a less dusty shot in the middle. Some velcro and some quick disconnects and it could be removed in seconds.
