Does a 2002 Ford Ranger Extended Cab have the r c plugs in back of the stock stereo? My brother is installing a pair of subs for his friend and needs to know, thanks for any help.

 

there is not a stock radio made that has rca outputs....
your choices are to either buy a line output converter (knock-down) to turn the speaker level into rca level, or make sure that the amp has high-level inputs...
