Metra 72-9300

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 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.

Cant go wrong with wiring harnees

Pros: Beats cutting wires and using electrical tape.

Cons: None at the moment.

Worked fine, with a little tape.

Written By Anonymous, the Washington, DC Area on Monday, January 19, 2015

Crutchfield Customer Review (What's this?)

I used this harness as I replaced my worn-out factory speakers in my 04 Subaru Outback. It connected fine to each replacement speaker (Kenwood KFC-1665S), but the other end of the harness didn't connect perfectly with the plastic connector on the car itself. The piece on the car has a little latch that is meant to lock it securely to the connector on the speaker wiring, but the Metra harness didn't have a corresponding place for that latch to take hold of. I just had to push the Metra harness onto the car's connector as far as it would go, and then secure it with a wrap of tape. Not ideal, but it worked.

Pros: Price

Cons: Not a perfect fit

Does exactly what it was made for

Written By Monir, Huntington, NY on Sunday, January 11, 2015

Crutchfield Customer Review (What's this?)

Wiring is appropriate length, not too long and plenty to wire up neatly. Connectors make it simple to install the infinity primus speakers I got, simple well made connectors plug and play back to my stock Subaru door wiring. Does the job exactly as it was made to.

Pros: Does exactly what it was made to do, Crutchfield service to help figure stuff out

Cons: None

Crutchfield Customer Review (What's this?)

Great product! As specially when Crutchfield added these for free with my speaker purchase!!! Easily allows aftermarket speaker installation without having to cut and crimp new connectors. Plug and go these in to connect aftermarket speakers for a hassle free install that looks factory!

Pros: Easy install and Crutchfield adds these for free with many speaker purchases. These are the main reason I order from Crutchfield.

Cons: None

Effortless install

Written By GreggS, Georgia on Sunday, January 04, 2015

Crutchfield Customer Review (What's this?)

The speaker harness made connecting my new speakers effortless... simply plugged them in with no cutting of the original wires in the car.

Pros: Made installation simple - no wire cutting required.

Cons: Not an exact fit for my '03 Subaru Forester.. Had to spread a clip on the subbie's connector and tape together as a safety to keep the two connectors together.

Crutchfield Customer Review (What's this?)

Allowed the install of aftermarket speakers with no wiring modifications.

Pros: Do the job great!

Cons: If i had a con it would be the lack of a "lock" on the adapter to the factory wiring harness. Nothing electrical tape won't cure.

Crutchfield Customer Review (What's this?)

Had to expand female connectors a little to fit the speaker male terminals. I wish the ends that connects factory harness had a locking system as the factory did. I simply used electrical tape to ensure connection plugs didn't seperate.
