Speaker Polarity App Reviews

App functions fine. Please increase the level of the generated speaker pop though as it is very low

This little app saved me a huge headache when replacing the factory speakers in my truck and figuring out which speaker was out of phase. It works as described and the developer offers a free downloadable test tone that can be burned to CD. It makes the testing process very quick. Once the wiring was corrected, the improvement to the overall sound in the truck was fantastic. Great app. The app is still scaled to iPhone 4/4s screens, but it works just fine on newer phones.

THE BEST FIVE DOLLARS I EVER SPENT IN MY LIFE!!!! This is the best app I have ever used. Period. Something didn't sound right in my car stereo after upgrading the speakers, which required cutting the factory harnesses. It turns out the Crutchfield and other available schematics had the colors of + and - opposite to my car's factory wiring. It could be due to my car being a very limited run car (the only one I know of and that the dealers knew of). After spending a lot of money on a sound syst

I recently hooked up surround speakers in a house that was pre wired for them. Unfortunately whoever wired it chose to use plain wire without any indication of positive or negative. I was strongly suspicious that my speakers were wired backward, and I found this app. Sure enough one of the surrounds was out of phase, and after fixing it they sound dramatically better! This is one of those apps that is well worth the 5 bucks. I'm very pleased. Thanks!

Just built a new audio system in my car and I was struggling with some weird polarity issues coming from the OEM head unit. I downloaded and burned the WAV file to CD and played it on repeat. And then one by one I could test each speaker simply by hold my phone near it. Brilliant!

This app accurately identified the speakers out of phase. Bluetooth connected, turned on the test tone, held my phone in front of each of the speakers.

I ran the WAV click file from their website through my stereo (using my iPad), then held my phone in front of each speaker to check polarity. 3 out of 4 of my speakers were negative, so I reversed the wires on those. Very quick and easy.

Works great with Bluetooth, (doesn’t work when Apple Car Play is running, but does with Bluetooth) Within 2 minutes I was done. Found out 3 speakers were backwards, literally the most useful app I’ve ever downloaded.

I have it. I'm trying to figure how to us it. Would it be so hard to write STEP BY STEP INSTRUCTIONS telling how? like should i turn the signal output on or off? Like you say "select speaker type" Where would I do that?? How come you don't think about the user? It might be a good app, but you won't bother to explain usage. Is this digital, nonhuman, lack of understanding the other person's position ? Would it be so hard to present step by step instructions? Really! you put this up cause you e
