Review on 🔊 BOSS Audio Systems NX2800.1 Onyx Monoblock Amplifier - 2800-Watts, 1 Channel, 2-8 Ohm Stable, Class AB, with Remote Subwoofer Level Control by Andre Parsons

Bought this amp for my son's car to add to a Chaos Boss 4 channel amp which we are very happy with. I thought if the Onyx amp put out 50% RMS of rated power that would be more than enough, but NO. I connected 2 duel 4 ohm subwoofers with 400 watts RMS to 1 channel with a total load of 4 ohms. I estimated the power output to be around 500W to 600W RMS at 14V. I spent hours trying to get more power out of it using car stereo inputs, plugging directly into a spare battery and changing the way subwoofers were hooked up . NO DIF. Plugged into a 2 ohm subwoofer for a test, it defiantly outperformed 1 subwoofer, but nowhere near the advertised performance. I believe it will work with 2-400 watt subwoofers into 2 ohms. The cable connections on the amplifier are very good.
