Im adding an amp and sub to my stock Sony system that has Sync and NAV. I tried using the PAC FRD24 adapter and it doesn't work. Has anyone used an LOC that works with the same stock stereo I have?

 

i used a sni-15 pac module. what i did: remove the 3 bolts on your stock sub. flip the sub enclosure over, and take the two screws out holding the amp in place. they cut the wires coming out of the amp leading to the woofer.(4 white with blue, white, red, and black stripes), then connect the sni-15 to those wires, leaving the two brown wires black on the sni. Now you have rca imputs
