This amplifier features a one of a kind sound restoration system called Clari-Fi that analyzes your music as it plays. Using algorithms from default music samples, Clari-Fi is able to predict what notes were lost through compression, and restores your audio as the music plays! Compression can degrade up to 90 percent of the audio details originally recorded, so with Clari-Fi you will enjoy clearer vocals, purer harmonics for piano, and more dynamic music. The feature is the same one you will find in Lexus factory systems and in Harman home audio products, including a $15,000 Mark Levinson component!
Want to pass the controls to your friends? This amp is not only Bluetooth compatible but it also features Party Mode, which allows you to link up multiple Bluetooth devices to stream audio directly to the amplifier! Let your passengers stream their playlists directly to the amplifier and over your sound system!

Kappa K5 to keep my stock radio and provide BlueTooth features in my "classic"
I received my K5 amp from Sonic and was impressed immediately by the weight and size. It's compact for a 5 channel amp with a very solid and durable feel to it since it has a good amount of weight for the size. Before I even had a HU hooked up I synced up my BT through my Note 5 phone and was immediately impressed by the clarity and sound this amp helped push out of my new Kappa 693.11 and 462.11 speakers running all different genres of music. When I gave the wife a call from the included control panel she stated the call was very clear and was impressed that it didn't sound like I was talking on a speaker phone like her new car does. I am also impressed with how easy Infinity/HK made it to so I can now sync and play my music from my phones storage and add hands free capabilities to my "classic" car all through the included control panel. It might be a higher priced 5CH amp but I definitely feel like I got what I paid for and then some with this purchase.

Pristine Sound!! Great Build!!
I've owned this amp without issues for a year now and it still amazes me. It delivers clean RMS power to all channels , music sounds full and pristine at low volumes and just as good when I crank that gain up a bit at times no matter the genre. My setup is a 5 channel configuration with Infinity Kappa 60.11CS for my front doors, Infinity Kappa 62.11I for rear doors and Infinity Kappa-100.9W as my sub.I'm using a Kindle7 as my headunit and the Clarion EQS746 in line just as a voltage step up. Just to note, the sub channel delivers great power to my sub,it's actually much more than I expected. While the bluetooth feature adds versatility to this amp, i find the sound to be a bit distorted at higher volumes which is expected.The control panel adds a nice touch and the mic works well.Once paired with a smartphone, the calls are clear for both parties. The only bad thing I can say about it (which is great), is the hidden magnetic cover to the speaker terminals, since it was mentioned in the manual, it took me a while to locate [but thats the manual's fault :-) ]. Also to add , once using bluetooth as source input, make sure to switch the sub input to INT or no sound would be sent to sub output channel. Would have been great if this feature (INT/EXT selection) was added to control panel as I switch between sources often (Bluetooth/AUX) and would have to physically go to amp to make selection. Once again Pristine Sound! Great Build!
