Summary: The amp is exactly what I needed. It's pushing Infinity a pair of Infinity 693.9i 6x9's in the back and Infinity 50.9cs 5.25's in the front doors and it sounds unbelievable. Still have more than enough power to spare. Great amp, tight design and always cool to the touch.
Conclusion: 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).
Conclusion: I use this to power my Infinity Kappa series 6.5's & 6X9's. And it does an incredible job of it. Small size, big power, sleek design, Infinity is the only way to go for your mids and highs.
Summary: I bought this amp to replace a cheap 4 channel amp. Let me just say that it was truely a night and day difference! The minute I hooked it up, well I was hooked. I know that Infinity is not "known" for their amps, but this will start to change that. I currently have it powering Infinity Kappa 6x9's and Infinity Kappa 6.5 components, and let me say that these really come to life with this amp. I have the gains on both channels around 40% or so, and that is plenty.
