Rockford Fosgate Monoblock 2500 W Class-BD Constant Power Amplifier T2500-1bdCP

2,500 watts RMS x 1 at 1 ohm 1,500 watts RMS x 1 at 4 ohms (2,500 watts RMS x 1 at 2 ohms) Mono subwoofer amplifier Rockford Fosgate Monoblock 2500 W Class-BD Constant Power Amplifier T2500-1bdCP Power Series amplifiers actively monitor their speakers' performance using Rockford Fosgate's Constant Power technology. A speaker's impedance naturally fluctuates as it performs. So, just like your cruise control increases the engine's RPM to maintain your car's speed uphill, Constant Power maintains this amp's output by increasing its internal voltage and current when the speaker's impedance rises. This results in up to a 25% increase in the amp's total power output, especially in the crucial range below 50 Hz where a sub amp really has to shine.
