A low-noise preamplifier q-stasis stage reduces incoming noise from source units to improve the sound quality. With a signal-to-noise ratio of less than 90dB, you can listen to your favorite tunes without interruption in quality. Prewired inputs connect via RCA-nickel plated terminals that are high temperature and impact protected to provide secure connections. The PWM MOSFET power supply provides stable power through PC board with minimal heat generation and the aluminum heatsink dissipates heat quickly to allow the amp to run on lower impedance for a longer duration.\u003c\/p\u003e\u003cp\u003eThe 2 speakers have a peak power handling of 120 watts, RMS power of 60 watts, and an impedance of 4 Ohms, these bad boys know how to rock. They are protected from water, dirt, and UV protection against sun fade, and remain musical in all weather conditions.\u003c\/p\u003e\u003cp\u003eGet the sound you've been longing for during your fun activities with these MB Quart Marine Powersports Amplifier and 2 Power Sports Speakers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThis bundle comes with 1 nautic amplifier and 2 power sports speaker\u003c\/li\u003e\n\u003cli\u003e4-channel waterproof boat sound amplifier with marine-specific connectors built to withstand extreme weather and salt spray\u003c\/li\u003e\n\u003cli\u003eFeatures 320-watt maximum power output and RMS power of 4 x 80 watts at 2 ohms and 4 x 40 watts at 4 ohms\u003c\/li\u003e\n\u003cli\u003eVery smooth musical response, high output with minimal required amplifier power\u003c\/li\u003e\n\u003cli\u003eRemains musical in all weather and does not stiffen in cold\u003c\/li\u003e\n\u003cli\u003eMB Quart NA2-320.4 (1 Pack)\u003c\/li\u003e\n\u003cli\u003eIPX standard for water-resisting so you can confidently enjoy all of your music while on the water\u003c\/li\u003e\n\u003cli\u003eLow-noise preamplifier q-stasis stage reduces incoming noise from source units to improve sound\u003c\/li\u003e\n\u003cli\u003e4-channel operation with a flexible installation that allows for 4-channel or bridged mono mode\u003c\/li\u003e\n\u003cli\u003eRCA-nickel plated are high temperature and impact protected to provide secure connections\u003c\/li\u003e\n\u003cli\u003eAluminum heatsink dissipates heat quickly to allow the amp to run on lower impedance for a longer duration\u003c\/li\u003e\n\u003cli\u003eSimpatico coil design with PWM power supply keeps voltage constant through Ultra-Fi output devices\u003c\/li\u003e\n\u003cli\u003eQuick disconnect wires and RCA connections for quick removal during the off-season\u003c\/li\u003e\n\u003cli\u003eIncludes monitor thermal, overload, DC, and speaker short protection with lighted indicators for added safety\u003c\/li\u003e\n\u003cli\u003eSwitched OFF and HP crossover with complete control over amplifier signal\u003c\/li\u003e\n\u003cli\u003eAmp class: D\u003c\/li\u003e\n\u003cli\u003eTotal channels: 4 channels\u003c\/li\u003e\n\u003cli\u003ePower: 320 watts\u003c\/li\u003e\n\u003cli\u003ePower at 2 ohms: 4 x 80 watts\u003c\/li\u003e\n\u003cli\u003ePower at 4 ohms: 4 x 40\u003c\/li\u003e\n\u003cli\u003eCrossover: Electronic\u003c\/li\u003e\n\u003cli\u003eVariable high pass crossover at 12dB per octave: Switched Full\/HPF\u003c\/li\u003e\n\u003cli\u003eBass boost: 0 to 12dB at 45Hz\u003c\/li\u003e\n\u003cli\u003eVariable voltage: 0.2 to 9 volts\u003c\/li\u003e\n\u003cli\u003eSignal to noise: \u0026gt;
