I purchased this box to run 3 JLw3's in my 2009 corolla. The box is built well and is compact enough to fit in my trunk. I also stuffed the box to make up space. It's louder than 2 twelves. I can't tell you how well it sounds loud because the whole interior rattles, but at low volume it sounds solid and tight. My interior might be a little to small though. If space is a problem and over kill is not, I would recomend hightly.
