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. You can also call an Advisor for more information.

Wiring harness was useless. Not even close to fitting. But it was free so I guess no harm there

Made the install in my 86 suburban very easy without disturbing the factory wiring,just plug in,highly recommended.

Pros: makes the job plug and play

Cons: none

Plug it in, plug it in, or is it "Rub it in"?

Crutchfield Customer Review (What's this?)

My truck did not have the original speakers in it, therefore, I did not need these plugs for this install. They are a good product and would have simplified install had my harness not been altered already. With original factory plugs this would have been a great asset.

Pros: Just plug it in factory harness

Cons: none

Good product

Crutchfield Customer Review (What's this?)

Seems to be a well made product. High quality plugs. I didn't actually use these as my pickup didn't originally have front corner speakers, so I had to run new wiring.

Slick as can be

These little harness adapters are wonderful! Fit well, just need to tuck the extra down into the I/P. Made it a quick change.

Pros: Quick and fit well.

Cons: The extra wire & connector bodies may rattle -- need to be careful or wrap with insulator.

These were the completely wrong harnesses for this vehicle. The vehicle came equipped with round plugs and the harness was flat plugs. I did use the wires to connect the original harness with the new speakers tho.

I have a 1992 Dodge Ramcharger. The harnesses worked great for the rear speakers, but didn't math up for the door speakers.

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.
