FCT synthesis compares 5G/4G RF power amplifiers, highlighting GaAs HBT evolution, die layouts, and material innovations.

Summary - The 2025 Rivian R1T Gen2 audio amplifier outputs 960 watts across 16 channels driving 19 speakers, representing a reduction from the previous generation's 1,200-watt, 18-channel configuration. The system features native Dolby Atmos support and is branded as "Rivian Premium Audio," replacing the previous Meridian Audio partnership. A significant architectural change relocated the amplifier from under the driver's seat to under the passenger-side dashboard, aligning with Rivian's Gen2 vehicle platform. The system includes a dedicated subwoofer, height speakers for spatial audio processing, and is offered as a $1,750 option on base trims while remaining standard top configurations.
