LAS VEGAS, CES Booth #9827 (January 8, 2009) - Pioneer Electronics (USA) Inc. gave two of its car amplifiers, the GM-6400F 4-channel and GM-5400T 2-channel, a cosmetic makeover, providing consumers with an amplified car audio listening experience that looks as good as it performs.  Both amplifiers were treated with a splash of red on each side of the RCA and speaker terminal inputs for added appeal when displayed in custom installations.  The heat sinks (shroud) were revamped utilizing a rectangular shape with a black matte finish to complement the aesthetics of the GM-D8400M and GM-D7400M class D mono amplifiers in the same series.

"Adding an amplifier boosts the overall sound of any audio system in both quality and volume.  Pioneer's two new polished GM amplifiers provide the sonic qualities of more expensive amplifiers for a fraction of the cost," said Larry Rougas, vice president of marketing and product planning for the mobile business group of Pioneer Electronics (USA) Inc. 

Enhanced Design Benefits

The newly designed heat sinks of the Pioneer GM-6400F 4-channel and Pioneer GM-5400T 2-channel amps ensure maximum heat dissipation due to the sub heat sink placed on top of the main chassis.  The corrugated (mesh) allows for more heat to be released when the temperature rises especially in high volume levels to help achieve a constant operating temperature and high reliability.  Both amplifiers incorporate a black outer heat sink complemented by a removable brushed aluminum center and a blue LED power indicator. 

Although unseen in normal applications, the amplifiers adopt the H-shaped bottom chassis from the top-of-the-line PRS-A amplifiers to eliminate vibrations and resonance caused by constant movement of a car, so the listener better hears the sound delivered by the amp ensuring a richer sound experience.  

Both amplifiers feature fixed crossover networks and speaker level inputs enabling the amplifiers to be added to virtually any audio system. 

The GM-6400F and GM-5400T are available for a suggested price of $160 and $200 respectively.
