share on:

Press Release:

Holly Hill, FL – Axxess® will introduce two new all-in-one AX-DSP Packages at this year’s CES, designed to retain the OE functionality for digitally amplified systems. Packages include the patent-pending Digital Signal Processor (AX-DSP) by Axxess, a vehicle-specific T-harness and amplifier bypass harness.

For Hyundai/Kia 2010 and up* vehicles with SPDIF digitally amplified systems, the AX-DSP-HYKIA2 will retain the ability to work with the SPDIF digitally amplified system, and includes the AX-DSP and a plug-n-play harness.

For GM 2014 and up* vehicles with MOST50 digitally amplified systems, the AX-DSP-MOST1 will retain the ability to work with the MOST50 digitally amplified system, and includes the AX-DSP and a plug-n-play harness. It will retain features like text message reading, navigation prompts and OnStar®.

For both of the AX-DSP Packages, the amplifier does not need to be retained and installation of the AX-DSP must be done at the amplifier location.

AX-DSP Plug-N-Play T-Harnesses

Axxess is doubling their current line of AX-DSP Plug-N-Play T-Harnesses, by introducing nine new solutions at CES for select Chrysler, Honda, Hyundai, Kia, Nissan, Mazda, and Toyota applications. These vehicle-specific T-harnesses will significantly reduce the AX-DSP installation time for installers.


New for 2018:

AX-DSP-CH3 for Chrysler 2011-2014

AX-DSP-HON1 for Honda 2010-2014

AX-DSP-HON2 for Honda 2016 and up*

The AX-DSP Fills a Gap in the Market

The AX-DSP is a cost effective solution for customers who want to retain their factory radio and improve their vehicle sound quality, while still retaining systems like SYNC® or OnStar®.  This digital signal processor sets itself apart with on-board digital amplifier turn-on capability, chime retention with volume control, and fully adjustable 31 band graphic EQ with time delay. All features and adjustments are controlled via Bluetooth® to the Axxess smartphone application, available for iOS and Android devices. The AX-DSP, which began shipping in the summer of 2017, already works with a wide range of vehicle applications, including non-amplified vehicles that do not have chimes. For amplified vehicles or vehicles with chimes, see the AX-DSP application chart for more information.


Now, with the addition of these nine new T-harnesses, the AX-DSP can be installed into a wide range of vehicles, even faster than before. With the introduction of two new AX-DSP Packages, a complete solution is available for the digitally amplified MOST50 and SPDIF systems for select and Hyundai/Kia and GM applications.
