Summary: I had got a pair in a box when I got my car stereo upgraded, I got them free with the package, their very good. Kicks great and not bad for the price. Had them over a year and one just recently blew, so I order a replacement from here!
Pros: I was looking for replacement subwoofers for my home stereo and was not willing to buy a whole new setup. These 8 ohm 12" Kenwoods are a much improvement over the stock. The magnets are huge and that only means power. They are a perfect power match for my Denon in the old Sony Speaker cabinets.
Cons: The mounting area was a little larger and the cabinet needed slight enlarging to accommodate the speaker properly.
Summary: I purchased this as a TEMP replacement for my ($250.00) Kenwood kfc-xw1222d that popped. I am shocked at how well this "cheap" sub is performing. I made no changes to my amp settings and it is just taking every watt I got. I'm getting the same performance for $200 less.
