Watch a full tutorial as a 2020 Chevy Silverado will have four new Skar Audio 8" subwoofers and Kicker 1800w RMS amplifier installed. We will also be using an AudioControl LC2i and Epicenter for our line out converter and signal EQ for our amplifier. These amp and subs will be integrated to the factory audio sound system.

Note: This vehicle was equipped with the Bose amplified system from the factory. We will be retain the Bose audio system fully, and this install only integrates into the factory subwoofer for signal. If you do not have Bose, you will need to obtain your signal from your rear door speaker channels or behind the factory radio.

This video applies to Chevy Silverado or GMC Sierra trucks for years 2019, 2020, 2021, 2022, 2023, and newer. This video also includes amp rack installation, wiring, and testing.
