It's putting out what I need it to.
I'm using this amp[lanzar heritage 2000w 2ch] to power 2 skar svr8. They are 4ohm wired down to 2ohm, 400wrms. This amp seems to be enough to power them to their limits, and more. Gain is pointing at the lower corner of "n" in "gain" to run a 50hz tone at 28acv both channels, slight backturn from half, bass boost is half and slight turn up. Running "through" seems to output most power and nice range on these subs, being rated for up to 350hz. I had a 120mm fan lying around and read that this amp gets warm, I cut out a square on the bottom shield plate. Attached the fan blowing into amp, with only 2 screws and that created bow at openings on opposite sides to allow an easier outflow. It does get pretty warm even with air moving now. For the price it's powering is useful for about half the price of the "properly" matched amplifier's and that is to assume those would need to work at full power to put out what this can at a bit more than half. This was reviewed after ~2 weeks~ break in.
