These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings.

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."

Includes Crutchfield's 60-Day Total Satisfaction Guarantee

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

Features

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

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

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

Quick-Slide Terminal Measurements: The positive female quick-slide terminal measures 0.205" (inner width), while the negative female quick-slide terminal measures 0.115" (inner width).

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

Very Handy

Written By TroyB, Tallahassee, FL on Monday, October 27, 2014

Crutchfield Customer Review (What's this?)

Made installing the speakers to the factory wiring a breeze.

Pros: Easy Install No cutting of stock wiring connectors

Easy to use, preserves stock wiring

Written By Jason -, Austin, Texas on Monday, October 20, 2014

Crutchfield Customer Review (What's this?)

While these aren't necessary to complete an installation, they sure do make it a lot faster. Instead of having to splice into the existing wiring, this clips onto the new speaker and then connects directly to the OEM wiring harness. Worked perfectly, and included for free with my order, so it was a win all the way around.

Pros: easy to use speeds up installation retains factory wiring harness

Cons: none

Speaker wiring harness worked great

Written By Gary, Lampasas, Texas on Sunday, September 21, 2014

Crutchfield Customer Review (What's this?)

I had to replace the door speakers in a 2008 Silverado that quit working. I ordered the speakers from Crutchfield and the harness, mounts, and instructions were included with the purchase. The harness worked perfectly! I unplugged the old speakers, put the wiring harness on those connections and then connected them to the speakers. It was that easy! Mounted the speakers and then reinstalled the door panel. No fuss!

Pros: Quick and easy, plug and play

Cons: None

Harness review

Written By Derek k, Berea ky on Friday, August 22, 2014

Crutchfield Customer Review (What's this?)

Harness had to have a small strip of plastic cut off the connector to fit the factory connector. Once sliced off, it fit well.

Pros: Fit snug with snap closure style. Better than manually combining wires.

Cons: Did not fit without adapting it.
