Great amp! Big power! Stable and efficient!

Hi guys, just a review on this amp for you guys. At first I was skeptical about it as it is a very small amp and the power ratings doesn't seem promising. I went on to purchase with my gut and hope it turns out well. Also the reason I had very limited space in my car.
Self installed it under the passenger seat, fits like a charm. Now comes the testing stage. This amp was installed to power 2 sets of speakers. A Focal Access 165AS and a JBL GTO coaxial speakers. Both speakers rates at 80W RMS where the amp states only 63W RMS x 4 channels. Turned it on, did some settings on the crossover and stereo. Then I start to crank up the volume to 35 on my Pioneer deck. I can say that the highs are clear (not audiophile like the Audisons), the bass was strong and hits hard on the mids as well as the coax at the rear. I pushed the gain up to about 70% and the speakers started to distort, I was in awe. What the heck? The speakers should be able to take more if you match the RMS ratings so I took my eBay bought RMS test kit to check the actual power it shows. At 70% gain on the SA amp, it shows 83W RMS on each channel with +- 3W RMS on every other. I was literally amazed, played it at the same setting for about 30 mins. Touched the amp and it was warm but not hot. You can still lay your fingers on it. Stopped and opened up the amp, double sided PCB and the components that I don't understand but look good though.
All in all, for such prices I would recommend this amp to anyone. Now time to push the gains higher and see what happens, might even test it with a 300W sub and see if it cuts out.
