This amp might be the best-designed piece of electronics in your vehicle- your WHOLE vehicle. At its core is a PWM regulated MOSFET power supply, generating 300 Watts of big, clean power. Total harmonic distortion is less than 0.005% (1kHz, 4 ohms), and terminals, inputs, and outputs are gold plated to guard against corrosion. The PRS-X340 offers a bridgeable 2/3/4 channel capability for system flexibility, plus variable crossovers so you can fine tune your system. The Premier two-year warranty applies.
