I just installed my 2 12" Rockford Fosgate P3's, Rockford Fosgate 801S amp and Sony head unit. It's the first time I installed a headunit before and I'm not sure what else I need to do. My stock speakers in my 95 Jeep Grand Cherokee don't work now. I hooked up all the wires from the stock head unit wires to an adapter to my sony head unit, but didn't do anything with the stock amp. What do I need to do to get the stock speakers to work? My subs and head unit work fine. I'm a newbie at this.
