FD speaker wire polarity
I'm st to go, and I have my new rear 5x7 infintys mounted, but now on the right side I cannot tell what wire is positive,a dn what wire is negative!!! I usually go by the "hot" colored wire is positive , and the "cold" is negative. but now on the right rear wires, there is a biege wire with a blue stripe, and a blue wire with a beige stripe!! anyone know what to do to find out which is which, or know hwat one is positive?

I figured it out now. the beige wires with the blue stripes on both left and right side were positive. I found a good way to always find out too.
If the polarity is not shown on the speaker so you know what wire is positve, you can use a 9V or any other battery to do this ( I used a 7.2V from an RC car). say on the speaker there is a blue and a brown wire for example. touch the battery or wires to the terminals. if you touch the positive side of the battery to the brown wire and this speaker sticks out, then brown would be negative. if you put the positvie side on the blue wire's side, and the speaker went in, that is the positive side. taht's how I figured it out.
