The Pioneer GM-D8601 is a Class D mono amplifier designed to drive powerful bass systems in your vehicle. It delivers flexible power options depending on your setup, providing 300W at 4 Ohms, 500W at 2 Ohms, and reaching 800W when running at 1 Ohm, which allows you to connect up to four subwoofers for a more intense sound experience. This compact unit measures 6 x 26.5 x 20 cm and weighs 2.7 kg, making it easy to tuck away in tight spaces while maintaining a clean black finish. To help you fine-tune the audio, it includes a built-in low pass filter with an adjustable cut-off between 40 and 240 Hz and a dedicated bass boost remote for quick adjustments from the driver's seat. With a signal-to-noise ratio of 100 dB and a wide frequency response starting at 10 Hz, it ensures that your low-end frequencies remain clear and distortion-free.
