Component Description: DSP
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The DSP is a power amplifier for the vehicle speakers. The audio input signal comes from the ACM via the Automobile Audio Bus (A2B) cable. It may drive all speakers on a vehicle or share the speaker output with the ACM.
The DSP requires PMI when it is replaced.
