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.

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.

Metra 71-017C Speaker Wiring Harnesses

Written By Jeff, Battle Ground WA on Saturday, January 17, 2015

Crutchfield Customer Review (What's this?)

Fit perfect although the speaker connectors were a tight fit although probably a good thing because there not likely to pop off. just be careful when putting them on so that you don't break the speaker terminal off.

Pros: Perfect fit

Cons: None

Perfect Fit

Written By Toycatfish, Florida on Sunday, December 28, 2014

Crutchfield Customer Review (What's this?)

Perfect fit in my daughters 2004 Saturn l300. No to cut and splice wires.

Pros: Snug fit on my kenwood speakers. Perfect fit to factory harness. No need to cut any wires

Cons: none

Makes the install so quick and easy

Written By Buckley C, Washington on Sunday, December 21, 2014

Crutchfield Customer Review (What's this?)

This is probably the quickest way to simplify the installation for any install. I have bought these for all my applications and really takes the pain out of the installation. With these I always get the polarity right on the install. The design on the Jaguar stock connectors gave me a little trouble on a rear speaker. not the connectors fault but the stock plugs design. I always buy these and have them pre connected before I take the speakers out to do the install.

Pros: Simple, fast and guarantees I get the polarity correct.

Cons: They are cheap but more expensive than cutting and splicing the enclosed wires to the stock harness.

Audi/VW/Porsche speaker wiring harness

Written By eturk, California on Friday, August 08, 2014

Crutchfield Customer Review (What's this?)

This is the correct speaker adapter for 2001 Porsche Carrera 996, Boxter, etc. Look all over the Internet and Crutchfields the only place I could find. Hopefully they'll update the description to include the cars this fits.

Really helpful on front dash speakers as it's difficult to cut the stock harness, attach connectors, then have enough length to actually attach the speaker. Get these, they're worth it!

Pros: worked perfectly! Plug into existing harness in seconds.

Cons: none

Perfect for Porsche 996 Speaker Replacement

Written By ScottG, Portland, OR on Tuesday, June 03, 2014

Crutchfield Customer Review (What's this?)

I used these speaker wiring harnesses to connect to the dash and rear side panels of my Porsche 996 without having to splice into the existing factory wiring bundle. The plug end was a perfect match for the Porsche plug and the spades fit tightly to the new replacement JL Audio speakers. Plug and Play!

Pros: Affordable Perfect Fit

Cons: None

Written By Adapter Wire Harness defect, Bellbrook, OH on Monday, November 19, 2012

Crutchfield Customer Review (What's this?)

One of the four harnesses was defective in that it was missing one electrical terminal, so I had to cut and manually solder this harness to the speaker. This was not beyond my skill; however, the main reason I chose Crutchfield was so that I would have an easy installation job.

Cons: The particular item I recieved had a manufacturing defect.

Not for your Saturn Vue

Written By Edward, Boston, MA on Saturday, April 12, 2008

Crutchfield Customer Review (What's this?)

This harness was
provided for free to
install replacement
speakers in my 2004
Saturn View. Don't
use it.

While the connector
snaps together, the
wires inside made
poor contact,
causing the sound to
cut in and out as
the I drove my car
around. I had to
disassemble my door
3 times before I
figured out the

Soldering the wires
together was a much
more reliable
solution in the end.

Thanks for the free
harness, but no
thanks if you have a
Saturn Vue.
