Championship Performance

C300.2 Championship Performance:

"This amp sounds great, and is almost indestructible, as befits a member of the Polk/MOMO family. Considering the quality of the sound, the fit/finish, and the reliability of the C300.2 I'd say this amp is a keeper."

Car Audio & Electronics

  • Polk's Massive Dynamic Headroom (MDH) Power Supply uses multiple smaller-value capacitors wired in parallel to lower the Equivalent Series Resistance (ESR). This lowers impedance for more efficiency, faster transient response, more instantaneous power peaks, tighter bass and better control.
  • The MDH Power Supply features oversized Toroidal Transformers to more easily deliver high voltage, high current power. This set of tremendous transformers lowers the incidental radiation of stray magnetic fields for uncontaminated audio signals.
  • Oversized Power Supply BUS Bars achieve maximum power transfer from the MDH Power Supply to the audio circuitry for more efficient high voltage, high current output stages.
  • Better Sound.
  • Power Supply "Choke"? Inductor reduces stray noise effects from power cables and alternators, cutting ground loop disturbances for truly quiet amp performance.
  • High current Bipolar Output Transistors with low impedance pump maximum voltage and high-current to your speakers. Dual low noise Operational Amplifiers at the input gain stages deliver higher gain & wider bandwidth at a faster "slew" rate (with the ability to change voltage "on the fly"), for excellent transient response.
  • High-end Non-Inductive Metalized Film Capacitors in the active filter stages for excellent transient response and extended bandwidth with low noise and low distortion.
  • Surface mounted Metal Film Resistors are used in the audio signal path, delivering higher performance with lower noise and less fluctuation ("value drift") over time. MFR technology is so stable that your music will sound perfect for the life of your amp.
  • High damping factor at the speaker output terminals improves driver control for tighter, punchier bass.
  • More Control.
  • While most amps have an input sensitivity up to only about 2 Volts, Polk's Variable Input Sensitivity ensures high performance even with older, low-power head units by accepting 200mV up to 8 Volts, and allowing Line Level (RCA) or Speaker Wire inputs.
  • Fully adjustable electronic crossovers power any install using virtually any speakers on the market.
