Alpine PDX-F4 400W 4-Ch. Power Density Series Digital Amplifier

Alpine PDX-F4 Car Stereo 4-Channel 400W Digital Amplifier Power Density Series

Alpine has received a 2010 Design and Engineering Award from CES Innovations for their In-Vehicle Audio category. Their next-generation PDX amplifier series (PDX-M12, PDX-M6, PDX-F6 and PDX-F4) is designed and engineered with great performance that gives amazing sound quality, power performance, and reliability.

The PDX-F4 is built with a Class-D 400 Watt Four-Channel powerhouse while at the same time keeping a small profile enabling placement in vehicles with limited space. Alpine has incorporated a whole new design with the power supply with highly sophisticated thermal and voltage protection, low noise and high efficiency. The PDX-F4 delivers 100 Watts per channel and can also switch to a 2-channel mode to drive subs with 200 Watts each.
