Overview

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

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. You can also call an Advisor for more information.

They worked great and made installation a breeze.

william from Metlakatla, AK on 11/1/2016

2003 MINI Cooper
Crutchfield Customer Review (What's this?)

These are sooooo much easier than soldering fittings together to adapt the old plugs to the new ones. one thing that i would suggest however is buying a wrap to muffle the vibration. when there is a lot of base coming over the speakers, the plugs may vibrate against the frame of the car. i have yet to find the right wrap but that would be the only downside to these plugs. great job Crutchfield!

Pros: super easy plug and play.

Cons: just need to be wrapped against vibration

Convenient hook-up for factory wiring harness.

Pros: Quick connect and go with my 2003 Toyota Land Cruiser.

Very sleek, I was looking for an alternative to the factory power antenna and decided to do away with the oem hole, this tucked away nicely into the corner of the dash and gives me better reception than the factory setup!

Pros: One wire hookup made it a breeze and can be mounted virtually anywhere out of sight and provides excellent reception

Connor from New York, NY on 9/8/2015

2002 MINI Cooper
Crutchfield Customer Review (What's this?)

I was a bit weary of placing an order for new speakers for my 2002 MINI Cooper as I had never done any electrical or stereo work on a car before, but Morgan from Customer Support reassured me that installing speakers on this car would be a simply process and that I could handle it no-sweat. Sure enough, he was right. Crutchfield included everything I needed to install a pair of Kicker 40CS654 speakers into my car. This adapter, the Metra 72-9301 Speaker Wiring Harness, was the key that enabled me to connect these new speakers to the connector in the door of my 2002 MINI Cooper without having to split any wires or solder anything.

Pros: Easy installation No soldering required

Cons:

No Matching to 2002 Sequoia

Anonymous from MV, CA on 10/27/2014

2002 Toyota Sequoia
Crutchfield Customer Review (What's this?)

It didn't fit to 2002 Sequoia speaker connection and didn't match to it. I didn't know how they advertised that fit to Toyota Sequoia on Crutchfield webpage. Do they really know their stuff? I gave 1 star for it didn't have 0 star.

Pros:

Cons:

Crutchfield response on October 28, 2014 This is one of the reasons why we suggest that customers give us a call before ordering, just to make sure they're getting the correct gear. The 2002 Sequoia is one of those oddball vehicles that use different speaker connectors in the front doors and the rear doors. This harness will work for replacing the front speakers, but not the rear door speakers. Give us a call and we'll send you the rear door harness if that's what you need.

perfect

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.

1 question already asked

It doesn't look like we have a wiring harness available for that vehicle. You may have to cut off the factory connectors and splice the vehicle's speaker wires to your new speaker wires. If you have any additional questions on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation in your vehicle. [ Kenny  Jan 16, 2016 ]  Staff
