Metra 71-004C Speaker Wiring Harnesses

These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if these adapters are compatible with your vehicle. Warranty: 60 days.

Note: Some aftermarket speakers have terminals that are wider than this harness's slide-on connectors. You may need to widen the harness's female slide-on connectors, or use the slide terminals that may be included with the speakers. If you need to connect your new speaker's connectors to the Crutchfield harness, soldering is best, and crimping is also very popular - see "Accessories."

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

This materials are awesome! It made the installation easy and quick.

Features

Crutchfield Speaker Harness: Crutchfield speaker harnesses prevent having to cut your vehicle's factory speaker wiring when replacing the factory speakers with aftermarket car speakers. Each Crutchfield speaker harness features two female quick-slide connectors on one end that attach directly to your new aftermarket car speakers, and a proprietary connector on the other end that connects to your vehicle's factory speaker plug.

Quick-Slide Connectors: The Crutchfield speaker harness is equipped with large (positive) and small (negative) female quick-slide terminals. These quick-slide terminals fit directly onto most aftermarket car stereo speaker terminals (slight crimping may be required). In the rare cases that the quick-slide terminals do not fit your new speaker terminals, you will need to replace the quick-slide connectors on the Crutchfield speaker harness with the correct size terminal or solder the Crutchfield speaker harness to your aftermarket speaker's terminals.

Note: Installation tools, hardware, and accessories are not included and sold separately. Please see the Accessories tab for recommendations and availability.

Quick-Slide Terminal Measurements: The positive female quick-slide terminal measures 0.205" (inner width), while the negative female quick-slide terminal measures 0.110" (inner width).

Wire Code Chart: Two identical Crutchfield speaker harnesses are included.
