Great!

The amp/box/speakers sound and look great. I ordered a Kenwood head unit also so I would have sub control and not lose the Kenwood quality sound between the amp and head unit. The sound is great!!!!! The price is even better, with the head unit included I only spent around 375.00 total. It sounds as good as some sound systems I have installed that cost between 1000.00 and 2000.00 dollars.
DONT BE AFRAID of the Hifonics subs, they are not high end cost, but they are high end performance, they are dual voice coil. If you series/parralel bridge the subs & amp for 4 ohm load using all the coils it will produce great bass. The amp performs as expected for a Kenwood, top notch. The box is built very good and looks great too. Im not too up on buying online since it hurts local business but with prices like this you simply cant pass them by. Oh yeah shipping was good too. Hope this helps you decide on a purchase.
