To protect your speakers and amplifier lifespan, we don't suggest you use FP series /DSP series/other some digital power amplifiers that are not marked as suitable for 2ohms under 2 ohms. 

We are developing new digital power amplifier, which can work at 2 ohms for a long time.  D series digital power amplifiers support 2ohms stable operation. The models are as follows
