I have a 2010 Mazda 3 and these are the front speaker wires I have a multimeter but I'm worried I'll screw something up somehow...but does anyone know which is (+) and (-) ?

Never mind I figured it out

What was your problem and what was fixed?

The only reason I ask is it may help someone later down the road.

I wasn't thinking I cut off the harness when I could've just got an adapter of some sort but the yellow and blue are positive and the yellow and green were positive...

Or just use a multimeter
