Rockford Fosgate T1000-1bdCP
Power Series mono sub amplifier — 1,000 watts
About the Rockford Fosgate T1000-1bdCP
Powerful bass
Rockford Fosgate enjoys a reputation for building high-quality mobile audio products. Their Power Series amps are the top of the line, with proven durability and proprietary technologies that deliver stronger, more reliable performance than most other amps out there today.
High-tech solutions yield more power
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 range below 50 Hz.
Tough construction, huge bass
Rockford Fosgate builds each Power Series mono amplifier with heavy-duty, state-of-the-art components. The award-winning Dynamic Thermal Management design manages the temperature of the internal components, distributing heat evenly for higher efficiency and less distortion. The unique heat sink allows the heat to escape more efficiently so the high-power output transistors stay cooler and last longer.
1,000 watts!
The T1000-1bdCP mono sub amp uses an efficient Class bd design to deliver up to 1,000 watts to your subwoofer system from a very compact profile. This amp can even drive a 1-ohm load, so you can get massive bass out of a variety of system designs. The variable 24/dB per octave crossover creates a more natural sounding transition from your speakers to your subs.
