Works as expected

The amp is working as expected nice power and it offers the ability to adjust gain and cut off which is helpful when trying to tune the system.
Build quality is poor this due to my amp arriving with both adjustment knobs pushed in a bent.
This did not happen in shipping (as the amp was well packed) so it was in the build and as such this should not have passed QC at the factory.

Sonic requested photos which I sent but did not peruse the issue as the damage did not affect the amps performance and circumstances (I was out of the country and the car was at the installers) prevented me from returning the amp for a replacement.

It was not Sonics fault as the amp was sealed but they are the seller so the responsibility lays with them.

This amp is the best

I did lots of research before i spent my hard earned money , and this amp is more than expected it has lots of power running it @ 2 ohm and it delivers every watt that it says and then some . I would say if you need some major power look no further because this amp is awesome .

Great buy

Awesome product. Great small compact size. It has a good weight to it as well. Solid amp. I'm running a 10" NVX DVC and at 4 ohms this thing sounds great. Quality bass and clear when you set it up correctly. I would recommend it all day.

Lots of power

This thing has plenty of power when testing the rms power in 2ohm it goes beyond 750rms it reaches a solid 785rms with good 4 gauge power cable that is also nvx. I definitely recommend this amplifier.

Great value

I would recommend this amp to anybody.
Only downfall is the set screw for the remote turn on was stripped quite easily. Other then that its awesome.

Good little amp on kicker Q Class.

Put this amp on a 10” round kicker Q Class in a jeep. My Jeep never has doors on it so I wanted something cheap incase of water intrusion or theft. Have a brand new kicker 800 watt amp in my car. I Am serious about car audio. I have built systems in at least 9 of my own vehicles since I was a boy. I am 38 now. I Can’t tell a difference in the power. I would say this amp will suffice for 90% of car audio builds. Will look at this brand again in future.

Best amp I have ever owned with real power

I love this amp replaced it after using the 500x1d prime amp which is good but this amp is perfect for what I am running in my SUV I think I'm going to get 2 nvx subs and see how it sounds with 2 because my on 12 hits so hard off this little powerful beast
