GT5-A604

640-watt, four-channel power amplifier with subwoofer output for upgrading car audio systems.

The JBL® GT5-A604 has a lot of raw force – and it’s all under your control. This a 640-watt power amplifier is composed of four full-range amplifier channels that you can configure to run in four-channel mode, in three channels (two full-range stereo channels plus two channels bridged to amplify a subwoofer) or in bridged two-channel mode (for high-power stereo applications). There’s also a variable-bass EQ to tune the amp’s operation to your liking and a bass-boost adjustment control that empowers you to determine how much bass you want. A built-in variable electronic crossover (12 decibels per octave) ensures that each speaker in your system receives an appropriate band of frequencies. Pre-amplifier outputs facilitate easy system building and wiring architecture while eliminating the need for high-loss Y-adapters or signal splitters. And a large, cast-aluminum heatsink firmly controls operating temperatures. All GT5 Series units feature common-dimension footprints, a feature that minimizes the amount of space required and hence optimizes multiple-amplifier mounting applications. The end result is high technology that produces studio-quality audio within your car. Your favorite behind-the-wheel songs will sound like new.
