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.

Perfect

Crutchfield Customer Review (What's this?)

Perfect! They matched right up with the Toyota connectors.

Pros: Good fit: The connectors all match, and the wire length was just right.

Cons: None.

Perfect fit on my Toyota!

Did not fit

Written By Devin, oregon on Monday, August 12, 2013

Crutchfield Customer Review (What's this?)

I ordered two of these for my 1993 Toyota Tercel. I was installing (2) Rockford Fosgate P16's and (2) Rockford Fosgate P142's.

1. They fit into the front door stock harnesses easy.

2. The prongs were too small to fit on the negative and positive terminals to either speakers.

^^ Had to snip these off and add our own.

3. The rear speakers, didn't even have the right harness.

^^ We had to remove the stock harness from the stock speaker, and put it on the already changed aftermarket harness.

Pros: Fit the front door speakers Had wires we could use

Cons: Did not fit terminals Doesn't fit rear dash speakers
