In this video, we show a step-by-step guide to removing the OEM amplifier and subwoofer and replacing the amplifier with an aftermarket 7-channel NVX bundle, using the GROM Amplinq Amplifier Retrofit and DSP Interface, custom harnesses and connectors, and an amplifier bracket.

We are also replacing the subwoofer with an aftermarket sub and using the GROM Audio Subwoofer Ring adapter.

This video is a part of the GROM Audio Amplinq Car Sound Upgrade Project.
