I'm running (2) infinity kappa 6.5 ,two tweeters with two infin...ity crossovers as well as (2) infinity kappa 6/9s in my 05 impala . It's sounds nice , clean and crisp. Also running a JL 1200/1 HD amp with (2) JL w6s in a superbass pro box . They really compliment each other . I would recommend.

This amp is built really with very good conn...ections, crossovers, filters and design. The 4ch portion is ample with good sound. My only complaint here is with the single sub channel. I connected a 10" Infinity Kappa sub at 2 ohms and should have gotten 350w rms to it however the sub sounded way too quiet no matter what I did. I bought a different sub set up and same issue. I decided to keep the amp for the 4 channels and purchase a Kappa One monoblock amp for the sub to see if it helps. Will find out soon.

Th...e amplifier came defective out of the box, I used to be a professional car audio tech, cable supervisor and electrician. I know my way around electronic devices, this amp as soon as I put power to it, it would cycle on and off quickly. I know its a factory refurb, but it should work better since they should have got the kinks out of it after it fault the first time. I have hence sent it back immediately to the factory and have tried to get a response as to the status of the item that they sent me defective in the first place. Their response has been that they have forwarded my email to the proper representative. I dont know if and when I will get another replacement unit, or when the turn around time for the repair of the one I sent them back. Basically I'm very disappointed with Harman Kardon, I ve had several of their receivers and home amplifiers and thought it was a great company, but in all fairness I ve not had to have them serviced.
Incredible piece, lots of adju...stability in sound, compact design makes it fit where other amps won't. plenty of power to run a average system, pushes a pair of 12" infinity reference series just fine. If you're looking to build a moderate system for your vehicle, you will not go wrong with this amp. Looking to build another system in the wife's HUMMER and probably going to use a KAPPA FIVE to run that system too. Clarity, adjustibility and ease of consealment, this amp does it all.
it's a... 5 channel and high end series of infinity but the sub woofer output does not work (it does produce bass but barely audible compare other 4 chanles that I still hook up from the head unit. Called for support and get a run around that I did not know what I am doing. I did a test after talking to a tech by borrowing a 2 channel amp (cheaper than the infinity I paid for) from my brother-in-law's that I just installed. Now I can hear and FEEL bass that I suppose to hear. Now trying to call them up for since last night but they put me on hold for long time. And they just hung up on me as I am typing this comment.
