GM Genuine Parts Rear Side Door Speaker 15201406 - OEM Sound Restore

In this review of the GM Genuine Parts 15201406 rear side door speaker the bottom line is simple: this is a direct, factory-spec replacement for owners who want to restore the original sound character in compatible GM vehicles. The unit is manufactured to GM OE specification, so it delivers the same fit, form, and function as the original speaker and makes installation straightforward for DIYers and technicians. If your factory rear side speaker has failed or sounds thin, this GM-recommended replacement is the quickest path back to the intended in-car audio balance.

Key Features

• GM OE specification: Built to the same fit and form as the factory speaker so it installs cleanly without modifications.
• Factory-replacement design: Manufactured and recommended by GM to restore the original audio tuning used in the vehicle from the factory.
• Durable construction: Offers the reliability expected of original equipment components for everyday driving use.
• Plug-and-play capability: Designed to mate with the vehicle harness for a quick replacement that generally requires minimal tools.
• Audio restoration: Reproduces the same mechanical voice coil and cone movement principles as the original, improving clarity and balance if the old speaker was degraded.

Who It's For

This speaker is aimed at owners of compatible GM trucks and SUVs - including Yukon, Sierra, Tahoe, Suburban, Silverado, Avalanche and Escalade models from the late 2000s to early 2010s - who prefer to keep their audio system stock and maintain factory sound quality. It suits DIY installers who value a straightforward, plug-in replacement that restores the original audio behavior without needing custom adapters.

It is less suited for enthusiasts seeking upgraded aftermarket performance such as increased power handling, deeper bass, or high-end audiophile clarity; those buyers should consider component or higher-spec coaxial upgrades rather than a direct OE replacement.
