Speaker Adapter Spacer Rings SAK114_55 - Fits Rear Doors of Select GM

Our review of the Speaker Adapter Spacer Rings SAK114_55 concludes this is a practical, no-nonsense part for anyone upgrading rear door speakers in compatible GM SUVs. The single biggest reason to buy is the trouble-free fit: the adapters are 3/4' deep and use existing vehicle mounting points so installers can mount most 6 1/2' aftermarket speakers without cutting or drilling. For DIYers who want a clean install and installers who value repeatable fitment, these spacer rings remove common clearance headaches.

Key Features

• Depth control: The 3/4' depth prevents interference with door internals and ensures the aftermarket speaker clears the window and mechanism.
• Direct mounting: Uses existing vehicle mounting points so installation is straightforward and does not require fabricating new holes.
• Speaker opening: A 5 1/2' round cutout is provided to house most 6 1/2' aftermarket speakers while keeping the speaker centered and stable.
• No cutting or drilling: Eliminates the need for irreversible modifications to the door panel or metal, preserving vehicle integrity and resale value.
• Pair included: Sold as a pair to cover both rear doors of a single vehicle for a consistent matched installation.

Who It's For

The SAK114_55 spacer rings are ideal for vehicle owners and installers replacing rear door speakers in select GM SUVs who need a reliable spacer to avoid clearance issues. They suit people who prefer a reversible, bolt-on upgrade that keeps factory mounting points intact.

These adapters are not for someone who needs universal fitment for non-GM doors or for installations requiring custom speaker sizes; if your vehicle or speaker size falls outside the 5 1/2' opening or the listed fitment, look for a model designed specifically for that application.
