Where does it start/end? Do you have slack? Snowing outside and don't feel like going out to measure. Assuming I run the rca's from the stock amp, under the door sills all the way back to the navigation unit in the trunk. What length would be adequate.

 

Most of us will just add a loc to the factory sub in the trunk. I'm sure 8-10ft is more than enough if you went this route. I just bought a complete amp kit and used their rca cables.

I have over a 20ft rca video cable to my dvd player in the center console to my navtool located behind the factory navigation located in the trunk.

How are you doing your install?

I used a 19 from the stock amp to the trunk near the navi unit and have about 4' left over for slack.

 

I used three 15 ft RCA sets ... plenty of cable and about 4 ft in the trunk.
