The Pioneer GM-D7400M and Pioneer GM-D8400M digital mono amplifiers, intended for powering large subwoofers, use digital technology that make them 80-95 percent more efficient than conventional class A/B amplifiers. Due to the increased efficiency, the physical size of the new amplifiers was also reduced by 45%, making them more compact and easier to install.
“Adding an amplifier to an in-car entertainment system can dramatically change the overall listening experience, breathing new life into the car audio system regardless of whether it is installed in an older car or one fresh off the dealer’s lot. A better sounding car stereo system equates to a better driving experience,�?
said Larry Rougas, vice president of marketing and product planning for the mobile business group of Pioneer Electronics (USA) Inc.
“With these GM series digital amplifiers along with our shallow subwoofers, consumers no longer need to sacrifice space to add more bass.�?
The Pioneer GM-D7400M and Pioneer GM-D8400M also feature block-style terminals that allow power and speaker cables to be securely connected to the amplifier without the use of crimped-on spade terminals. In the 2- and 4-channel versions, the amplifiers accept speaker-level inputs for easy integration to factory OEM audio systems.
For many car audio enthusiasts, looks are as important as sound quality, and Pioneer’s GM series of amplifiers offer a smooth, refined look. Each has a black heat sink complemented by a brushed aluminum center and blue LED power indicator.
Large cast aluminum heat sinks are used for increased heat dissipation for cooler operation with tremendous reliability. Oversized power terminals and speaker level inputs offer more flexibility in installation while the built-in crossovers provide better audio control.
