Speaker Polarity

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.

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?

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!
