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.

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.

Speaker wire harness

Written By CG, Junction City KS on Friday, July 05, 2013

Crutchfield Customer Review (What's this?)

This harness was exactly what I needed. Purchasing it allowed me to make a very handy non-standard tool for clearing SRS (air-bag fault light) indications on my Honda Civic. I crimped this harness to a toggle switch, and created a tool that is far more handy and durable than the standard tool. ...and I did it at a fraction of the cost :) Although, clearing the SRS light is an ease procedure, accessing the wiring can be difficult, and jumper-ing the wiring (in a tight space) can by awkward. TAH DA... harness to the rescue!

Pros: ...Ease of use, inexpensive, this model not carried elsewhere (although many Honda's, on the road, still use this particular model number). ...Mates securely, more versatile than the newer replacement models, makes the job easy.

Cons: none noted

The harnesses were extremely helpful and dumbed down and reduced the time involved in this installation exponentially. Great product made even better because it was free. Great Job Crutchfield!!!

Crutchfield Customer Review (What's this?)

When I saw i was getting Honda speaker harnesses I was a little uneasy because
my car isnt a Honda. Its a Mazda but the harness worked perfectly. Didnt need to
do any rewiring to put in new speaker replacements. Keep in mind, if you are
wiring to an external amp(not going through your head unit), you wont need these.

If you don't already have these in your toolbox, you may find them handy, if not indispensable.
Some speakers have non-standard connectors. Make your installation easier with connector adapters.
