Amp for Subwoofer

What power is the speaker rated at? I used to have a subwoofer that was
rated at 300 watts RMS, 1200 watts peak. At 8 ohms, that is just under
40 amps RMS at rated power, 150 amps at peak.
The situation is actually a lot more complicated, as speaker impedances
are reactive, depend to a degree on cabinet design and vary with frequency.
NHT SW2: 10" woofer in vented enclosure. Frequency response: 21Hz-350Hz, ±3dB direct in. Crossover: 130Hz (passive version, built-in). Sensitivity: 89dB (2.83V at 1m), 200W maximum. Impedance: 8 ohms nominal, 6.2 ohms minimum.
I'm going to go ahead and configure the amp (which does NOT have a beefy power supply) for mono mode and try it out.
