RMS Power @ —Ω: Look for — watts RMS (not peak/max)
Stable @ —Ω: Amp must be stable at this impedance or lower
Monoblock/Class D: Most efficient for subwoofers
CEA-2006 Certified: Ensures honest power ratings (optional but recommended)
💡 Power Matching Guide: The ideal amp provides 75-100% of your sub's RMS rating for daily use, or 100-125% for louder setups. Avoid exceeding 150% to prevent damage.
⚠️ Low Impedance Warning: Your final impedance is below 1Ω. Not all amplifiers are stable at this load. Make sure the amp you choose specifically lists stability at —Ω.
