Axxess Technologies AXDSPX-HN2 Plug-and-Play DSP Harness for 2016-Up Honda

Axxess AXDSPX-HN2 Plug-and-Play Harness

The Axxess AXDSPX-HN2 is a vehicle-specific T-harness and interface kit designed for select non-amplified Honda models from 2016 onward. It enables a plug-and-play connection between the factory wiring and an AX-DSP digital signal processor, which must be purchased separately. The kit targets installers and enthusiasts who want to add advanced audio tuning without cutting or splicing the original harness. It supports behind-the-radio placement for a clean, reversible installation.

Bundled Accessories Expand Control and Integration

The package includes the AXDSPX-HN2 interface, a dedicated interface harness, the vehicle T-harness, and a wired bass knob. The bass knob provides direct level control for a connected subwoofer amplifier. System settings are managed via a Bluetooth-enabled mobile application compatible with Android and Apple devices, offering a 31-band graphic equaliser, independent high-pass, low-pass, and bandpass filters per channel, and per-channel delay up to 10ms. Configurations can be read, written, stored, and password-protected within the app.

Straightforward Install with One Firm Requirement

Installation is described as easy and plug-and-play behind the factory radio, using the pre-wired harnesses supplied. The critical constraint is that the vehicle must be a non-amplified model; amplified factory systems are not supported. The AX-DSP processor itself is not included and must be sourced separately. Firmware updates are applied via a Micro-B USB connection. No splicing is required, preserving the vehicle's original wiring integrity.
