Metra 82-3013 & 72-4568 Speaker Adapters and Harness - Vehicle Audio

In this review of the Metra 82-3013 speaker adapters paired with the Metra 72-4568 speaker harness, the bottom line is straightforward: this combo is for DIYers updating door speakers in late 90s to early 2000s GM cars who need a direct-fit, OEM-style mounting and a simple plug-in harness. The adapters are designed specifically for 1997-2004 Chevrolet Corvette doors and accept 6', 6.5' and 6.75' aftermarket speakers, while the harness is intended for select GM vehicles and can repair or replace damaged speaker plugs. The single biggest reason to buy is fit and compatibility that reduces modification time and helps preserve the factory wiring.

Key Features

• Vehicle-specific fit: The 82-3013 adapters are molded to match 1997-2004 Corvette door openings so aftermarket speakers install with minimal trimming.
• Multiple speaker sizes: The adapter accepts 6', 6.5' and 6.75' speakers, enabling common aftermarket choices without custom brackets.
• OEM-style material: Made from automotive grade, high-temp ABS plastic to resist heat and maintain shape in door environments.
• Plug-and-play harness: The 72-4568 harness connects speakers to the factory wiring harness for an easier, cleaner installation or repair.
• Repair capability: The harness can be used to replace plugs that were cut or damaged, restoring factory connections without splicing.

Who It's For

Car owners and installers replacing factory speakers in a 1997-2004 Chevrolet Corvette who want a near-stock installation will appreciate the Metra adapters. The set is also useful for general GM owners who need a compatible speaker harness to avoid cutting into the factory loom and to speed up installation.

Those who should look elsewhere include buyers needing a full speaker mounting kit with multiple ring sizes included for non-Corvette doors or anyone seeking metal brackets for heavy aftermarket woofers; some users reported mixed impressions of material thickness and limited ring size options, so heavy-duty custom installations may require alternatives.
