The Audio System Italy AD3000 is a Class D monoblock amplifier designed specifically to drive demanding subwoofer systems. It delivers substantial power, reaching 1200 W RMS at 4 Ohm and scaling up to 1800–1850 W at 2 Ohm, while remaining stable at a 1 Ohm load where it provides 3000 W. To maintain sound quality, the internal circuitry uses high linearity components with low thermal drift, which helps keep distortion low even when operating under low loads. Fine-tuning the bass is handled through a low pass filter adjustable from 40 to 180 Hz and a subsonic filter ranging from 10 to 50 Hz to protect the speaker from frequencies that are too low. You can further shape the response using the 0 to +12 dB bass boost or adjust the phase between 0 and 180° to align the subwoofer with other speakers. A wired remote regulator is included, allowing you to manage the volume from the driver's seat. Measuring 640 × 232 × 56 mm and weighing approximately 8.26 kg, the unit is built for those who want deep, powerful bass without sacrificing stability. Its efficient Class D design ensures that power losses are minimized, making it a reliable choice for high-performance car audio setups.
