What matters for this product

Open Help Centre
Should I compare RMS power or maximum power? Use the continuous or RMS ratings at the stated impedance for meaningful matching. Why does speaker or subwoofer impedance matter? The final load determines whether the amplifier can operate safely and how much power it can deliver. How do I match a subwoofer and amplifier? Compare continuous power at the final wired impedance, then verify enclosure and electrical requirements.
