I installed an amp and upgraded speakers on my motorcycle. Took great effort to install everything according to my wiring diagrams.
After it was all done my front speakers just didnt sound right. Same speakers as the rear but nowhere near the quality as the rear speakers.
I took the bike apart to check my work. I did it right but using a multimeter I discovered that the original bike wiring was wrong. POS and NEG wires were backwards even though color coding and connectors were correct. Strange I know.
I fixed it but something was nagging me about it. Was the factory wiring really wrong? Could it really be?
Researching and double checking my thought process on what I discovered and "repaired", I came across this app. How simple could it be.
5 minutes after purchasing I verified that now my speakers are indeed wired correctly. All I can say is THANK YOU! I only wish I could have had this before I redid the wiring to show me it was audibly wrong at the time. Better late than never and the piece of mind is well worth the price of the app!!!
