Conformal coated crossover components protect against fresh and salt water spray as well as dust and sand. IPX67: YES - Tested to the highest Marine and Motorsports standards for resisting the elements. Tweeter materiaL: Titanium Dome Tweeter - Very smooth musical response, high output with minimal required amplifier power. Marine certified crossover: Marine Certified Crossover - Conformal Coated, Butterworth 12dB per octave crossover with PTC (Positive Thermal Coefficient) tweeter protection. Dimensions: 22.6 x 13.5 x 16.75 in. Features of NA2-400.2: MB QUART NA2 400.2 400w 2-Channel Amplifier Amp For Polaris/ATV/UTV/RZR/CART. Marine Grade Protection: Yes - Amplifiers are ABYC & ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture. Pre-Amp Circuitry: Q-Stasis Pre Amplifier Stage - The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality. Inputs: 1 Pair, RCA Nickel-Plated - High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. Operation Mode: Two channel operation - Flexible installation allows this amplifier to run in two channel or bridged mono mode. Crossover / Signal Shaping: Switched FULL / LPF / HPF - Complete control of amplifier signal, essential when using two or more amplifiers. Class / Topology: Full Range Class D - Highly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink. Output Devices Technology: PWM MOSFET Power Supply - Stable power through the PC board with minimal heat generation. Heat Sink: Aluminum - Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration. Power Supply: Simpatico Coil Design - The dual coil Pulse Width Modulated power
