T500-1bdCP

The Rockford Fosgate T500-1bdCP from the high-end Power Series is a powerful 1-channel mono amplifier featuring innovative Constant Power technology. Thanks to its Class bdCP circuitry, the amplifier delivers a constant output power of 500 watts RMS at both 1 ohm and 2 ohms. This makes it ideal for a wide variety of subwoofer configurations and offers a high degree of flexibility in impedance matching.

The built-in Punch EQ bass boost allows for targeted amplification of low frequencies by up to 18 dB. In addition, a variable low-pass filter and a switchable infrasound filter ensure precise adjustment to the connected subwoofer. High-quality MOSFET technology, a solid aluminum heat sink, and comprehensive protection circuits ensure reliable power output even during demanding bass applications.
