Metra 71-031C speaker wiring harnesses

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

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-supplied 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.

Crutchfield made my difficult project easy. Changing out the old sound system in my 2000 Jeep Cherokee was a task I didn't look forward to as I am not one to solder and wire anything really. With the easy connect wiring harnesses sent with my speakers I had nothing more to do that push and click my new speakers in and all is well!

I didn't know these existed. I installed some Polk speakers in my wife's 07 jeep and spliced the wires for the install,no big deal. My son bought the same speakers for his 2000 Jeep and we were looking around on the Crutchfield site and came across these and the custom brackets for the 4x6 dash speakers. It was a no brainer and the fastest install I've ever done.

Got as part of an overall stereo system replacement. Earlier, I had replaced the front speakers and had to solder the old adapters onto the new speakers. It wasn't overly difficult, just odd angles and tricky. With these things, it's just slide on the lugs to the speaker terminals, and click into place. Super easy !!!

I work in the car alarm & stereo business & put these in many cars & trucks for people who want the best, but at a cheap cost, when it was time to upgrade my own system, I called my distrib. & asked for a discount, their price for ME was higher than Crutchfield & it would have cost me additional money for the faceplates, converstion parts, etc ????? I always delt with Crutchfield on my other cars & went on line - WOW I saved over $100.00 between the radio, speakers,and ALL the parts i needed to install - bottom line, I AM IN LOVE WITH MY SYSTEM !!!!!!! & saved money, I now know why my customers come back & send friends for the same system !!!!!!

Always Check Polarity

Written By Chris S., Elkwood VA on Thursday, June 21, 2012
Crutchfield Customer Review (What's this?)
 
Always check polarity, don't assume that connectors come wired up correctly for your application as they likely fit many different vehicles and configurations. Luckily I had access to a wiring diagram for my 1999 Chrysler LHS with the factory Infinity II system. After observing that the polarity was opposite of how the connector adapter was wired, it was easy enough to switch the terminals in the connector. There is a white/grey plug that pops out. Once removed, you can look inside the body of the connector and see little plastic arms that lock the terminals into the connector. Gently release them with a small screw driver, then the terminals with wires attached slide out the back. Pop them back in opposite of how they came out until you here a click, reinsert the plug, and you are good to go.
Pros:
Makes for a clean install without splicing wires.
Cons:
Polarity may need to be reversed for your application.

I have a very odd Jeep Wrangler model, the 2002 Apex. The harness for the sound bar speakers works fine, but the front's don't fit. I had to cut off the connectors and connect them manually. The front speakers in this model don't look like speakers from other Wranglers I have seen. Still the connectors worked well on the soundbar speakers.

When you place an order with Crutchfield for your stereo needs, you get everything you need
down to the last little wire. You don't have to run out for speaker wires, or a harness,
because Crutchfield has you covered. The best part is your installation gear and guides are
free with your order. That itself is about a $20.00 savings. My Chrysler harness made things
so easy with installation. Crutchfield leaves nothing out, they want your installation to be as
easy as possible and believe me when i say it will be. Once again Crutchfield has you
covered.

Great product, fits perfectly. I replaced factory stereos in my 1997 Stratus
and 2000 Neon in about an hour each.

This harness was not even close to matching up with the connection in my 2000 Dodge Durango.


[Editor's Note: We apologize for the problems you encountered with your installation. Our database was recently updated with the correct harness for your Durango.]

Metra 71-031C Speaker Wiring Harnesses

Written By Nick A, Port Jefferson, New York on Wednesday, October 13, 2010
 
The connectors did not match the original equipment in my 2000 Durango. The Durango had a premium system with "Infinity" speakers (the speaker housing had Infinity and Chrysler printed on the back). Before buying, you should verify that they will work in your application.

They may work with standard type systems, I do not know. I had to cut off the originals and hard wire.

So easy, anyone can use these. My set had different size solderless connectors making
it impossible to mix up + and -. Mine came with the speakers....sweet!

Couldn't be Easier - And Works with Bass Blockers Too

Written By no7up, Spokane WA on Sunday, May 02, 2010
Crutchfield Customer Review (What's this?)
 
Couldn't be easier. One end plugs into stock connector, other end fits standard speaker spades. One large and one small spade so they can't get mixed up. Also makes it super-easy to install bass blockers - everything just plugs right in. Highly recommended!

I used these to mount Eclipse speakers in a 2002 Neon. They worked well - I just had to tie up the extra wire length to the speakers to keep the wire connector from rattling in the door.

Did not fit the harness plug. '04 PT Cruiser. OEM, not modified.

Had to remove connector and connect the hard way.

Nice idea and looked forward to using this, but it did not help.

These particular connectors did not match up to the factory ones. The male terminals were too wide to fit the more narrow female factory ones.

The harnesses slid right into the factory plug and I only had to adjust the tightness of the fit for the ends on the speakers. I can be sure that they won't be coming off anytime soon.

Didn't fit a 2000 Durango. Had to cut out the connectors from the factory speakers and solder the cables onto it.

These plugs have mail connectors that are too thick for the connector that's in the door.

Wrong Adapters

Written By Kevin, South Orange, NJ on Thursday, January 22, 2009
Crutchfield Customer Review (What's this?)
 
Simply put, these adapters didn't fit the harness for rear door of my 2000 Dodge Durango with the Chrysler Infinity system. It wasn't a gender issue; they simply weren't the right ones, although they were labeled for my vehicle.

Hi there. These could've been great if they were for a 2000 Dodge Durango, but the pins were too wide to fit the factory wiring plug in the doors so I ended up using 1/2 of the these harnesses and soldiered them to the original plugs that I took off the original factory speakers....

These harnesses made it extremely easy to hook up my speakers. All I had to do is plug the harness into my factory harness, and onto the slot on my speakers then I was finished. For a free item they work great. My only problem was that one of the harnesses wasn't working, but Crutchfield sent me out a new one.

2004 Dodge Stratus Plugs dont fit the factory plug fits this harness but the pins in the harness is too large for the factory plug. Also the factory plug has 2 guides on either side of factory plug.
Ended up crimping a connector onto the wire after tinning the end of wire with silver solder.

These little beauties made the installation of my new speakers a breeze. They plugged in quickly and prevented the need for soldering any connections. The only problem was that of the four harnesses I purchased one was defective. But Crutchfield responded quickly and sent a new harness that same day. Thanks!!!

Check First

Written By nikwbeach, Maple Valley, Wa on Friday, March 31, 2006
 
These things make it so much easier to install new speakers. Just click and go. If you own a PT Cruiser make sure you check to see what type of factory speaker plug you have. There are two types on the PT, a square plug and a square plug with a large groove on top and two small grooves on the bottom. The latter, which i needed, is part number 12071049.
