I bought the Factory Refurbished unit and I am very pleased with the product I got. Yeah, it has some scratches on the front that made it look a bit used, but it still has it's natural good looks.
As far as features go, well there aren't any. You get the basics, a bass boost and a low pass filter. It's a simple design and for me, there is nothing wrong with that. That is actually part of the attraction I have for this amp - a simple design with few controls, compact and lightweight, great price, with certified power. Details are a little slim on the thermal shutdown function, but the amplifier should turn off to protect itself in case of overheating.
I have this powering a sealed 8" subwoofer at 4 ohms, a very modest system for sure, but very enjoyable to listen to. I think this amp must be great for somebody who wants to add some low end impact in a simple configuration, without having to tweak too much. Performance is great in my setup. If you had a ported 2 ohm load, I'm certain this little amp could help rattle your car.
Pros: CEA 2006 certified power, compact, lightweight, simple attractive design, great price on refurb amp
Thank you, Crutchfield for offering great deals on Kenwood products through factory refurbishment!
Cons: No subsonic filter, no speaker level input, no preamp output, no signal sensing turn-on - If you want any of these features you'll have to look elsewhere. Kenwood DOES offer these features in some of their other models, just not this one.
