Check the listing for details. Wavtech linkAD Adaptive load module for universal applications (2-channel). Condition: New. Listed at 29.95 USD. The Wāvtech 2-channel adaptive load resistor module is engineered to make factory audio integration easier when upgrading to aftermarket amplification. Many modern OEM radios require a speaker load to function properly, and removing factory speakers can lead to reduced output, warning messages, or system performance issues. This module provides the proper load needed to help maintain normal factory radio operation while allowing the use of external amplifiers. Built with the same adaptive load technology found in Wāvtech amplifiers, it offers a reliable solution for a wide range of factory audio systems. The module can be used as a standalone integration device or added to Wāvtech amplifiers when additional loading is required.
