Metra 71-043 adapters

These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if these adapters are compatible with your vehicle. Warranty: 60 days.

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.

Crutchfield Customer Review (What's this?)

The rear door speaker wiring harnesses were different in my '98 Blazer LS than in the front and Crutchfield was on top of it. Just make sure that you add front and rear door speakers separately to your cart instead of updating your quantity.

Pros: Free!

Cons: N/A

Perfect fit for 4 door 99 Blazer

Written by: Tony from Ashburn, VA on September 30, 2009

These snapped perfectly into the OEM wire harness on the rear doors of my Blazer. A few things to note during your install however: if you are not soldering the ends, the speaker clip on the positive lead (the bigger of the two) will not fit through the hole between the OEM speaker mount and the door. You will have to modify it. I clipped off the tabs that were used to hold the old wiring in place and was able to squeeze it through fairly easily. Also, due to the length of the speaker harness, I had to rotate the speaker sideways in order to give the wires some slack. This is not really an issue, as the speaker still performs just fine and once the door panel is re-installed makes it very hard to notice. Lastly, (and more a problem for polk than the harness), there was a transistor on my polk 651dbs speakers that was placed very close to the positive speaker post. Because of this the plastic cover on the positive speaker clip gouged into the coating surrounding the transistor. So beware if you are installing those speakers. I gently rolled the transistor to the side when connecting the speaker clip and then let it press back on the clip afterward.

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.
