The Powerbass GTX15000.1D is a budget-friendly mono Class-D car audio amplifier designed to power a subwoofer or low-frequency driver with solid output and flexibility for small- to medium-sized systems. It’s a single-channel (monoblock) amp with a Class D design for efficient power delivery and relatively compact size, making it suitable for installations where space and electrical load are considerations.
Key features include adjustable input sensitivity and a wide frequency response (typically ~10 Hz–250 Hz), letting you tune it for deep bass performance, and a high maximum power rating (often advertised around 15 000 W peak, with real-world RMS output in the hundreds of watts depending on load).
Overall, it’s aimed at enthusiasts looking for an affordable way to add substantial bass power to a car stereo system without spending big on high-end amplification.
