Built-in Crossover In multi-speaker systems, it is important to make sure each speaker is sent only those frequencies it is designed to reproduce. This built-in crossover removes overlapping frequencies, ensuring greater efficiency, less strain — and a louder, cleaner sound.

Non-Fading-PreOuts The four-channel amplifier features independent RCA inputs for each channel. Internally, these are summed for the right and left signals to provide non-fading outputs for applications such as a separate subwoofer amp.

Speaker Level Inputs These terminals allow direct connection to factory-installed head units that don’t have preamp outputs, letting you add subwoofers to any system.

DC-DC Converter Power Supply The power supply uses MOSFET circuitry to convert battery voltage to the voltages needed for high amplification. The result is higher power and much wider dynamic range.

Adjustable Bass EQ This processing circuit provides optimum low frequency response, letting you adjust the bass for maximum clarity.

V-Power High-grade Components The rugged, road-worthy V-Power amplifiers deliver exceptionally high performance and provide detailed control. Available in mono, two-channel and four-channel configurations, these amps are as powerful as they are versatile.
