Absolutely Gorgeous
After having an unnamed Maxxsonics made 4-channel heat itself to death on me, I opted to bite the bullet and mate this to my Kappa Perfect 6 and Reference 6830cs speakers. One word: Amazing.for an amp that is literally, half of the size of the amp it replaced, it pushes twice as much power and is still cool to the touch. Sound quality was the primary purpose of my build, and it more than meets my needs.
Also, it looks beautiful.

Dissapointed
I spent a while looking for a good 4 channel amp to buy and I saw that this amp received good feed back. After having it in for almost a month, it blew on me. Now before you say I had my wiring bad, no, I had a solid ground with full contact, proper sized power and ground. I've had problems with the amp to what I was suggested it to be as clipping. I had the voltage input at about half and the vibrating from the speakers stopped and to add to that, the fuses didn't blow, the amp did, non of the protections worked. Maybe I just received a bad amp, but I surely won't be buying anything from Infinity again.

Awesome Piece
Powering 2 - 10" Kappa 100.9W's in bridged mode in an extended cab GMC pickup, tri-amped with active crossover. The sound is crisp, clear and as loud as you want it to be, but be prepared to upgrade your charging system - this amp will give your alternator a workout. A joy to setup, all settings are easy to configure and no tweaking was necessary after initial setup. The sound is fantastic, with no coloration audible. Highly recommend this amp to anyone looking for a clear natural sound. Sonic Electonix was great to deal with and any future purchases will definitely be through them.

Great Amp
The amp is great. It has fantastic sound, lots of power, and is easy to install and set up. The frequency response is good and it is easy to make adjustments. I am very happy with this amp.

Amazing
This amp is solid!! If the missing piece of your puzzle is an amp then look no further. I dont brag on shops often, but Sonic is the place to get your stuff. These guys know their s-it!! I explained what I had and what I wanted and they got me what I needed. I will definitely purchase from them again.

Kappa Four
Absolutely everything I wanted in an amp, plus a power rating that is very conservative. It is small, powerful, clean as crystal, has the right adjustments, and is very robust. You can use the front two channels to push all the speakers you want, and bridge the back two for a really conservative 300x1 @ 4ohm. I swear this back two channels bridged has driven my 2 4ohm jls (2ohm load) as well as my Kappa monoblock (rated 500rms at 4ohm). When set up in the livingroom against other considerations for my mids and highs, going from my other amps to the Infinity showed just full and musical the Infinity amp is compared to some lesser brands. Best I have owned, and it is not the most expensive I have owned.

Kappa Four
Had a powerbass amp before this one and the Kappa Four is definitely worth the extra $$. 2x cleaner and has extreme power for the compact design. Definitely enjoy the controls on the faceplate considering it is mounted on the back wall of my f150.

Great amp
The sounds is clear and crisp, love this amp. Much better than the MTX 4004 that I originally had. Does not cut out and runs quite cool.
