π§ Systems with limited installation space
Match power to your sub’s RMS rating: Pair this amp with a subwoofer rated for ~200–300 W RMS at your chosen impedance (typically 2 Ω) for clean, distortion-free bass.
Tune filters before boosting: Set the low-pass filter around your box’s tuning frequency first, then use the bass boost (2–6 dB) sparingly to add weight without muddiness.
Use quality wiring & proper fuses: Good gauge power and ground wiring, along with proper fusing, ensure stable power delivery and protect your electrical system.
Mind your enclosure tuning: A sealed box tuned slightly above resonance yields tight punch, while a ported enclosure tuned lower (~30–40 Hz) unlocks deeper bass.
