Memphis Audio VIV600.4V2 SixFive Series 4-Channel Car Amplifier

The folks at Memphis Audio are so proud of these amplifiers, they named the line after the year their company was born — 1965. Looking fine in its anodized brushed aluminum chassis, the SixFive Series VIV600.4V2 four-channel amp can send 80 watts RMS to each of your front and rear full-range speakers. Into bass? You can bridge this amp to 2-channel mode, and drive a couple of subs with 300 watts each. You can even change the color of the amp’s illuminated logo — select one of the seven available colors to match your mood, whim, or vehicle’s interior.

Active application examples

This versatile amp features onboard digital signal processing — including high-pass, low-pass, and bandpass filtering — that makes it useful in a variety of systems.

2-way system: the amp’s front channels drive a pair of tweeters, with a high-pass filter set to keep damaging low notes away. The rear channels drive a pair of woofers, with a low-pass filter set so the correct bass frequencies go their way. You can tweak the crossover settings to get the sound to fit your specific tweeters and woofers best.

3-way system: the tweeters are run the same way with the front channels, while you’d use the rear channels to power the midrange drivers, using a bandpass filter to eliminate the extreme highs and lows, allowing the midrange to play clearly. You’d use a separate amplifier to power the low-frequency speakers or subs in this type of system.

Connectivity and controls

A bass boost lets you add some extra pop to the bottom end. Speaker-level inputs and automatic turn-on circuitry allow you to connect this amp into almost any system, including ones using the factory radio. Preamp outputs can be used to feed a subwoofer amp its input signal in a 3-way system. A magnetic cover protects the control panel from dirt and other accidents.
