Audison Prima AP F1D - 1-Channel D-Class Monoblock for Subwoofers, 1000 W @ 1 Ω
The Audison Prima AP F1D is a compact 1-channel subwoofer amplifier that delivers high currents cleanly and operates stably even at 1 Ω. With up to 1000 W RMS at 1 Ω, you can drive even demanding woofers with control. Thanks to high- and low-level inputs, it works with both factory radios and aftermarket head units. Ideal as a powerful addition to the Audison AP F8.9 bit – for a full-fledged front/rear setup with a separate sub channel. Available at Carhifi.shop.
Technical Highlights
- 1 x 1000 W RMS at 1 Ω, 1-ohm stable
- D-Class efficiency, compact housing
- RCA (Low-Level) and Speaker-Level inputs
- ART Auto Turn-On via BTL speaker outputs (2–7 V, selectable)
- No internal, adjustable low-pass filter – perfect for DSP setups
- High damping factor and low distortion for precise sub-bass
Installation & Compatibility
You can connect the AP F1D directly to factory radios via high-level or to aftermarket units via RCA. The monoblock is designed for 1–4 Ω and delivers its highest power at 1 Ω. Plan for a solid power supply with the designated fuses (2 x 30 A) and sufficient cable cross-section. The Auto-Turn-On function (ART) simplifies installation in vehicles without a remote wire. In combination with the Audison AP F8.9 bit, a scalable system with a separate subwoofer channel is created.
