I have a 2007 Mustang Gt. It has the shaker 500 head unit and the subs in the doors. I just bought 2 12's to put in the trunk but im having a problem finding out where to hook the red and white feeds from the amp. The rem wire i can always hook to a fuse that turns on when the car does but i need to know if i need to buy aadaptor or are the red and white hookups in the harness but i just didnt see them. Any help would be great!! Thanks

on my gt i used a Line-Out Converter you hook it up to your rear car speaker it turns the high signal in to a low signal has a two channel rca out put to your amp and has a gain adjustment on convert so u can make it louder for more bass
