Metra 71-012C Speaker Wiring Adapters
These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings. 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. 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."

Features
Speaker Harness: These speaker harnesses prevent you from having to cut your vehicle's factory speaker plugs when replacing your factory speakers with aftermarket car speakers. The 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 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 speaker harness to your aftermarket speaker's terminals or replace the quick-slide connectors on the 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 speaker harnesses are included.

These adapters will make life very easy for you, especially if you have to put your stock speakers back in if selling your car. No splicing!!! Get these if you don't want the hassle of splicing, especially for cars with short wires!! I have an 03 Acura TL and they really helped me out!
