Harmony Audio Compatible with Chevy Suburban 1988-1991 Single DIN Dash

In this review the Harmony Audio Compatible with Chevy Suburban 1988-1991 Single DIN Dash Kit is evaluated as a targeted solution for owners restoring or upgrading original radios in late 80s and early 90s Suburbans. The bottom line: this kit bundles a Metra GM multi-kit, a Harmony Audio wiring harness, and a factory antenna adapter to make a clean, reliable conversion to a single DIN aftermarket stereo, and it is best for DIY installers who want to retain factory mounting points and minimize dash modification.

Key Features

• Complete kit: Includes the Metra 99-4544 multi-kit, Harmony HA-7016771 wiring harness, and a factory radio to aftermarket antenna adapter so installers have the wiring and trim needed in one package.
• Factory fit: The Metra multi-kit is designed to use original equipment factory brackets or the included bracket kit, which preserves the dash look and simplifies mounting.
• Faceplate options: Four ABS plastic faceplates are provided, including a flat 1/2 in and a 1/2 in with equalizer option, so installers can choose the trim that best matches the factory opening.
• Wiring harness compatibility: The Harmony HA-7016771 harness is made for select 1978-1993 GM and Chevrolet vehicles, providing a direct connection point to the vehicle wiring without cutting factory wires.
• Antenna adapter included: A factory radio to aftermarket antenna adapter is supplied to ensure the new stereo receives signal without extra parts or trips to a parts store.

Who It's For

This kit is aimed at owners of Chevy Suburban models from 1988 through 1991 who want to replace a factory or damaged radio with a single DIN aftermarket unit while keeping the dash appearance tidy. It is useful for mechanics and careful DIYers who plan to use factory brackets and value a documented harness that reduces splicing.

Drivers who need a specialty or nonstandard installation, such as custom dash fabrication, non-DIN head units, or integration with modern vehicle networks beyond basic audio, should consider a different, more advanced kit or professional installation. This package focuses on conventional single DIN swaps for the specified GM model years.

Frequently Asked Questions

Will this kit fit other GM models?

Is an aftermarket radio included?
No, the package contains the dash multi-kit, wiring harness, and antenna adapter only; an aftermarket single DIN stereo must be purchased separately.
