Bought new for $350 used in car for less that year when car broke down and havent used it since. 2 channel 220 watts per channel, 440 total watts.
More Power. - $100
* 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.
* The exclusive Polk/MOMO Pre-EQ Switch optimizes the amp’s active crossovers for use with Polk/MOMO Ultra High Performance Speakers and Subwoofers for perfect sound every time! In the C300.2, Pre-EQ is a dual-band fixed stereo EQ (LP: +9dB @ 40Hz bandwidth of 1/3 octave; HP: +2dB shelving EQ cornered @ 12kHz, Q of 0.707) for superb detail and accuracy with either Coaxes or Subs.
* Remote Subwoofer Level Control available separately.
Built To Be The Best.
* Industrial-strength extruded aluminum, supremely rigid and warp-resistant, with excellent heat dissipation for more reliable performance. Styled in conjunction with MOMO, maker of the world’s most sought-after bolt-on accessories, and featuring real Carbon Fiber accents.
* 6-Way Smart System Protection (SSP) circuits: Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto-Standby Mode ensure safety, reliability and durability.
* Selectable Subsonic Filters (15Hz@24dB/octave) for an extra level of speaker protection. Select ON/OFF via internal jumpers to keep subsonic frequencies from reaching drivers, preventing driver damage at high levels of low frequency play and reducing stress on the power supply for extreme reliability.
* Dual (top and side) computer optimized extruded aluminum Heat Sinks for more efficient power output, superior heat dissipation and high reliability.
* Double Layer Fiberglass Epoxy Printed Circuit Boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. Efficient layout safely packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.
* Removable cast aluminum End Caps offer more flexible install options, including an even smaller amp footprint.
* Power, Thermal and Short Protection LEDs easily visible on top plate.
* Hideaway Cover Plate conceals the wiring and the “Set It Once” user-adjustable controls for clean-looking, fiddle-free installs.
