Alpine PDX-M6 Car Amplifier
Alpine has updated and simplified their PDX amplifier lineup, with the PDX-M6 being the 'less-powerful' of the two. Still, the total output of at least 600 watts RMS at either 2 or 4 ohms is nothing to be scoffed at. This compact amplifier is of a Class-D design, so it runs cooler despite the smaller overall size. Another benefit of the PDX-series amplifiers is that they can be stacked on top of one another, reducing the amount of space needed for installation. With its sleek, versatile design, high overall performance, and reasonable price tag, there's absolutely no reason why the Alpine PDX-M6 shouldn't be a first choice for a subwoofer amplifier.
