Review on π Enhance Audio Quality with AUTUT Automotive Speaker Polarity Tester Phasemeter Tool by David Gagnon
A must for car audio lovers
Great tool. I managed to find one of the 8 pairs of speaker wire in my truck that I connect to the amps. It is important that all speakers are in sync (working together) and not working against each other. My new truck doesn't have a CD player. I was able to burn it to a flash drive using my laptop. Remember that lanes 3 and 4 are identical. Any of these will work to check polarity.
