fits and sounds perfect as a replacement factory sub in my Chevy 2002 Suburban. Factory sub was a POS. it is a 8" low profile in a sealed box... To make a long story short - it was disconnected while I had a box with tree top ported 12s in there, once we got our Bernese Mountain Dog - Subs had to go and I was left with a crappy factory sub. This one does the trick. Glad I went with a 2-ohm vs 4-ohm.
This sub in the recommended slot ported box and powered by a Kicker 400x1 amp sounds like a 10" or a cheap 12". The bass is deep and loud. I know these are subjective terms, but if space is a concern, or if you're not trying to win a spl comp, you will not go wrong with this beast.
