not that specific amps, but IMO i don't like kenwood amps, i've had bad experiences with them, and i know other people who have had bad luck with kenwood amps too
I dont know too much about them. The only person I know has three Infinity Perfect 12s and a kenwood amp and he shattered his rear window in his 04 tahoe
I had a similar model, the 9201D, and it was trash. overheated constantly, put out poor quality sound, etc.. the audiobahn A8000T is a better bet, IMO. That's what I got to replace it.
