Product Details: 520 Watt 4-channel amplifier. This is the same popular model that JBL makes for car stereos, only with coated electronics to stand up to harsh marine effects.
The GTO75.4's high-output MOSFET power supply ensures optimum power delivery into numerous impedances with low distortion.
The 75.4 comes outfitted with two variable 12dB per octave electronic crossovers allowing you to optimize system tuning based on speaker location and accompanying loudspeaker components.
Full range preamp outputs are provided facilitating multiple amplifier hookups without the need for high-loss Y-adapters or signal splitters.
