You are bidding on the Kenwood KRF-V5570D Amp. Active EQ, 5-mode DSP Built in Subwoofer AMP Dolby Digital,DTS Dolby Prologic, 100W X 6. The amp plays fine but with one problem in movie mode the amp will play fine but after a few minutes or so it will click off. If you turn the switch to Aux and then back to surround sound it will start playing again very annoying when watching a movie! Some one said to me it is just the switching mechanism and should be easy to fix. Aux - stereo and Radio we have no problems in these modes. Well I am no electronics engineer so I have just gone out and bought a new Sony amp. I must say the Sony amp is a bit disappointing compared to this Kenwood amp. Kenwood will blow the socks of Sony any day of the week and I will be sorry to see it go. You can really blast the music out with this one! 100% Feed Back every time!
