Hi. I try the search but not find and specific answer. The rear subs wires have four colors (red ,black ,green and grey).I need to know the polarity (+ -) of each one to avoid errors in the installation of new subs. Thanks for the help.

 

see if this helps :

see post # 11

I really don't think there is any polarity involved, could be wrong.

 

You are. Phase of speakers is MOST IMPORTANT.

 

Thanks. I am no audiophile, I seldom even turn the radio on.

 

Thanks to all.
Polarity is;
Black -
Red +
Grey +
Green -

 

Cool! This was very helpful. My son and I installed the PLPW6D's in his Crossfire and they worked well.

 

On the stock rear subs how can you tell which connector is + or -.
