hi, i am helping a freind install re audio xxx comps and i took off the tag that said if the red or the blue was the postive and i am wondering if anyone can tell me how to figure out which is which and or if someone has a set that might know.

If I had to guess, I'd say red is positive.

red is usually positive

Either way you shouldn't go by what they are labelled but by what sounds better. I don't own a vehicle and havent' where I run everything to its label. You should try ALL combinations of polarity when setting up your system.

Either way just attaching something to red is NOT the right way to do it.

While I agree with this for the tuning process, I think for the basiline you should start with everything in phase. Then make adjustments from there to determine best sound.
