Speaker wiring Question

9 posts in this topic

I was wondering if one wires a speaker backwards(swiching +-,-+) will it make a difference in sound quality? Knowing what I know about magnets, wiring one way the electromagnets attract the other magnet and the other they repel, but it seems that the speaker work anyways. I had to do some custom work on my 97 Grand prix to get some pioneers to wire to the factory plug. I just unsoldered the factory plugs from the factory speakers and soldered them to the new speakers. Seem to work fine and sound pretty good. Seems that other stuff I do it doesn't affect sound quality, does it damage the speaker any? Also does it affect tweeters, mids, and subs the same way, I would assume so but I know what happens then..

As a rule, I always go positive to positive, negative to negative. I think on some high end equipment, it can and does have an effect on the sound quality. On low end (Spark-O-matic stuff), it never really mattered.

I ran stuff back in the day, that I had no clue what side was connected to what. I heard my tunes. When I started getting into amps and sub box’s, I stuck to the plan.

[PoorWordUsage] whats up with that?

I have always been told that it does affect sound quality but can never remember how to identify - and + on audio systems?

Sorry didn't know that was a no no just tellin' the truth about the word. It won't happen again. I'd rather ask a question and not blow up my new stereo, than not ask and ruin some $200 electronics. I have no amp hooked up tho the factory speakers but my amp and subs will be going in next. I guess on the speakers that I put in their was noting marked so I did it, and hoped for the best. Did learn with the cutlass to disconnect the battery before any major electrical projects. laugh

Short answer is yes.

Low quality speakers with low power running to them you may not notice the difference. Hook up a 15" sub with a few hundreds watts running through it and you'll know.

If polarity is hooked up correctly, when the music "thumps" you should be able to see the speaker push out away from the magnet just a little. If polarity is reversed it will pull the speaker towards the magnet.

The big thing is if one speaker is wired one way than the other, then the sound waves will be 180 degrees out of phase. It may or may not sound bad. By moving around you can get this same effect. That is why rooms have sweet spots. You probably won't hurt anything, just affect sound quality.

+ on speaker wire usually is blank, - on wire usually has a stripe or the writing.

The wires were the leads directly leading to the electro magnet on the speaker, the bare copper. But now that you brought up the movement of the speaker I'll have to check it out. This wasn't a sub or anything, it was the front, door panel speakers in a grand prix.

If it was my amp, I would be very careful of reversing polarity, event though I have 20 bucks into the amp and subs. (gotta love rummage sales)

New question, I noticed when I was tearing stuff apart that the FBI rewired the antenna for a CB and left the AM-FM cord just a swingin' I have decent reception but is their a stock looking antenna that has both CB and AM-FM hookups? Or should I leave well enough alone.

    • I have been meaning to try to stick a yote too whenever I was out I hoped one would show up instead of a turkey.
    • should have set up in the grass! Uncle went back for evening set up at a pinch point hen and tom came through to go back to roost but no shot!
    • Beside the fun of fooling a turkey and sticking it witj my bow,this is why I love turkey hunting. Slow smoked with apple on the pellet smoker. 
    • Does anyone have a water driven backup sump pump? They look like the cats meow if you live in town. Or does code even allow them? If they are not allowed what is the best battery backup ones?
    • Got out Saturday morning. Perfect weather. Jakes and hens. Had a new group of 6 hens come in with no tom or jakes.   Did have a yote come out of nowhere right into my dekes. 12 yards. Just as I was drawing on it , it must have scented me and booked. A second yote crossed about 50 yards out. Sticking a yote is on my bucket list.   All in all a great morning.    
    • Good season Wild, onto next year. Should be some changes but I don't expect us to do anything crazy. Need to sign Granlund and Nino and that will use up a lot of our cap space. Can't afford Hanzel and possibly Haula and Vegas will be taking a player off our hands. I'm more interested to see who can sustain or step up their scoring next year or if anyone regresses. Granlund, Coyle, Nino, Zucker, Dumba, Spurgeon and Brodin all had career years, those are good problems to have. They showed us a lot but I think they still have room to grow and that is what we need. We have a nice cast of vets but they are likely too old to lead us to a cup, they would be in more supporting rolls. Hopefully our now seasoned young core and continue to build on their impressive seasons. Always disappointing to lose, even worse when you can't score against your old coach but I like the our team and hopefully we can keep getting better.
    • I'm not the most techy 40yr old out there, so I will try to explain what I'm looking to do and hopefully someone can point me in the direction I need to go. I have a cabin in the Chippawa National Forrest, no phone at the cabin and our cell phones dont work at the cabin either. My teenage son wants to take the wheeler and go riding alone. I worry he's going to get lost or if the wheeler breaks down he can't call my cell for help. When we drive my truck around; the gps in it works all the time.  I know I can put a GPS app on my sons phone so he can track his route in reverse to get back to the cabin. But what if he breaks down?  Does anyone know if there is a gps app that I could "pair" up me and my son's phone so I can see where he is at? kill 2 birds with one stone per say, he can use it to navigate himself on the wheeler and I can see where he's at incase I need to rescue him.  Thanks for the help.
    • Hit the Red River over the weekend for the 2nd time this spring. First outing wasn't great with a handful of smaller cats all under 10lbs. This weekend was a different story as we ended up with 15 cats Friday night. 5 over 10lbs, 2 of which were high teens fish. All caught on cut river bait.  Cats were on the shallow side of the river. Water was high and flowing pretty good. All fish were caught and released. Great night of fishin w no bugs to bother us and very nice weather! Gonna give it another whirl soon in a boat this time. Have a look!!
