thirdgenlxi Posted February 1, 2013 Report Share Posted February 1, 2013 (edited) I don't know if this has been covered here yet or not, but just ran into this so figured I'd put it up here since I know a lot of us are doing speaker upgrades. Not sure if anybody else uses these things or not, but I just replaced my rear speakers (went with some Polk Audio DB571... big improvement!!), and I don't like cutting into factory wiring harnesses so I got some of the Metra factory connector pigtails These... http://www.bestbuy.com/site/Metra+-+Speaker+Wire+Harness+Adapter+for+Most+1999+or+Later+Ford+Trucks/3866409.p?id=1051826168689&skuId=3866409 Anyways, I just plugged them in and didn't think anything of it, finished it all up and tried it out and it just didn't sound quite right, especially at higher volumes something just seemed off (the front stock speakers actually sounded a little better, lol). So I took it back apart and started comparing to the wiring diagram, and sure enough the polarity in these connectors is reversed. The spade connectors and wire colors are right on the pigtail part where it plugs into the speaker, but at the connector it's flip flopped from the factory connector. I tried using a pick to get the pins out of the connector to swap them and avoid cutting the wires, but they're kind of a one time deal and couldn't get them out, so ended up having to cut/splice the wires side to side. Much better now Just figured I'd give a heads up for anybody that might be using these. On a side note.... I'm liking these new speakers! Gotta do the fronts next, then sub and maybe HU at some point Edited February 1, 2013 by thirdgenlxi Quote Link to comment Share on other sites More sharing options...
Keepinitsimple Posted February 2, 2013 Report Share Posted February 2, 2013 I got those adapters too but I didnt notice this...I will have to check them out tomorrow. Would there be a way to tell besides pulling the panel off and speaker out lol Quote Link to comment Share on other sites More sharing options...

Would there be a way to tell besides pulling the panel off and speaker out lol Yea I think that's about the only way to tell is just follow the wires from the connector down to the spades on the speaker. I'm guessing they're probably all the same, so there's a good chance they are on yours too. You got a wiring diagram to see which is +/- in the factory connector?? I can look it up and screenshot if you need it Edited February 2, 2013 by thirdgenlxi Quote Link to comment Share on other sites More sharing options...
Keepinitsimple Posted February 2, 2013 Report Share Posted February 2, 2013 yes if you do not mind, that would be awesome Quote Link to comment Share on other sites More sharing options...
thirdgenlxi Posted February 2, 2013 Author Report Share Posted February 2, 2013 (edited) No problem... here ya go! (click to enlarge) Not sure which audio system you have or with/without rear DVD system, but it looks like the door speaker wire colors are the same for all of them Edited February 2, 2013 by thirdgenlxi Quote Link to comment Share on other sites More sharing options...
candurin Posted February 5, 2013 Report Share Posted February 5, 2013 I used them with my Infinity speaker upgrade and also had to swap polarity on all 4 speakers. Quote Link to comment Share on other sites More sharing options...
