JBL GTO504 4 Channel GTO Series Amplifier 280-Watt 4-Channel Full-Range Amplifier with Built-in electronic Crossover and variable Bass boost.
The GTO504 has been engineered to ensure optimum power delivery into numerous impedances with low distortion.
It comes outfitted with a variable 12dB per octave electronic crossover 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. The GTO504 is a great choice if you are looking to increase the output level of your current car audio system. To further improve your system's performance, we would suggest that that you also add a pair of JBL's GTO loudspeakers.
The GTO504 also features direct connect, which allows use of up to 4-gauge power and ground cable to ensure enough juice is being delivered. Direct connect speaker terminals are also used eliminating the need for additional adapters or special fittings. Common-dimension amplifier footprints are used on all of the GTO models providing two common dimensions for ultra clean multiple amplifier model installations.
