About this product

With a total peak power rating of 320 watts, the JBL® GT5-A604 four-channel, full-range amplifier with bass equalization features an electronic crossover to ensure a smooth transition from low to high frequencies. A bass-boost function gives low frequencies extra punch, while a cast-aluminum heatsink keeps the unit’s temperature under control. Full-range pre-amplifier outputs allow for multiple amplifier hookups without requiring high-loss Y-adapters or signal splitters. The result of all this high technology is studio-quality audio for your car.
