Buying Guide

Power ratings and RMS clarity

Look for realistic RMS power at 2Ω and 4Ω to match your subwoofer and avoid relying on peak wattage figures

Class and efficiency

Class D designs give higher efficiency and lower heat in tight car installs, which helps battery and ventilation demands

Impedance stability

Choose an amp rated stable at 2Ω or lower if you plan to bridge or run multiple subs to ensure reliable performance

Included wiring and protection

Wiring kits, built-in fuses, and protection circuits reduce installation cost and risk from miswiring or shorting

Gain, filters, and controls

Adjustable low-pass crossover, bass boost, and remote level control let you tune bass integration without changing head unit settings
