Overview

The Metra Electronics AXDSPX-HK4 is a radio DSP data interface designed to enhance vehicle sound quality by converting factory fixed analog outputs to multi-channel analog outputs. This allows for the easy addition of aftermarket amplifiers and speakers while retaining the use of OEM radio controls, including fade, balance, and volume. Installation is simplified with a standard T-harness that reduces setup time. The AXDSPX-HK4 offers 6 inputs and 10 individually assignable outputs, providing flexibility for complex audio systems. It features independent equalization on each output, with 31 bands of graphic EQ and separate time delay adjustments for each channel. Setup and control are managed through a free Axxess AX-DSP app via Bluetooth low energy, offering features like high/low level input selection, crossover adjustments, and patented chime cooling technology. This interface can be used in both amplified and non-amplified factory audio systems and includes a bass knob for subwoofer amplifier level control.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
