Metra Electronics 72-5602 4-Way Speaker Harness Connector for Ford & Mazda Vehicles, Multi Color

Worked great for 2016 F150 rear door and Alpine SPR-60 Coax Speakers.

Made install that much easier. No crimping/soldering... Snap, and youre done!!!

green wire is -, blue is +

Very easy to use plug and play.

Always good to have if you work on cars

I purchased two pairs of these, one for each door in my 2012 Mazda 3 I Touring Non-Bose Edition. For the back door/s I installed Kicker 46CSC684 and once I connected the adapter there was no splicing needed.
