Can you have subwoofer power and visceral excitement in your car? You can if you have the JBL® GT5-A3011 300-watt mono subwoofer amplifier. With a frequency response of 10Hz to 300Hz (–3dB) and a signal-to-noise ratio of 120dBa (reference rated power into 4 ohms), the GT5-A3011 clearly and cleanly delivers even the deepest, most powerful bass – and it’s driven by enough wattage (300W RMS, 600W peak) to make you feel every beat. But this mighty beast is under your control: You can set its input level and its built-in, 12dB-per-octave electronic crossover to tune your system’s bass as you like it. What’s more, its full-range preamp outputs enable multiple hookups without requiring you to use high-loss Y-adapters or signal splitters. Have fun out there.

Want power? The JBL® GT5-A3011 offers 200 watts RMS at 4 ohms, 300 watts RMS at 2 ohms and a whopping 600 watts of power handling at peak. That much electrical muscle means that your GT5-A3011 can play as loud and long as you want.
The GT5-A3011’s variable 12dB-per-octave electronic crossover allows you to optimize tuning based on your subwoofer’s location and accompanying loudspeaker components. And you can do it even if you’re not a rocket scientist.
With a frequency response of 10Hz to 300Hz (–3dB), the GT5-A3011 reproduces deep, teeth-rattling low frequencies without distortion. Whether you like a symphonic orchestra’s rumbling timpani or a hardcore rocker’s thundering bass guitar, the GT5-A3011 pours it out hard.
Clarity is central to the GT5-A3011’s mission. Its signal-to-noise ratio – 95dBa (reference 1 watt into 4 ohms) / 120dBa (reference rated power into 4 ohms) – gives you bass tones the way their creators meant you to hear them.
The GT5-A3011’s outputs allow for multiple amplifier hookups without high-loss Y-adapters or signal splitters. The sound goes out as clearly as it comes in – powered by all the volume that this powerful amp can muster.
