Okay i know that you know about this stuff so hopefully you know what i am on about.

I am thinking of adding a second head unit to my car due to my girlfriends refusal to carry an empeg around so she want a normal stero in the car.

I have no room for a second din but i do have room for another radio so the plan is to get a normal face off stereo and putting the main body stuffaway some where in the car and then have the face mounted in the dash.

Most face off stereos have about ten to fourteen connectors on the back, how would i see the longest cable i could get and what length do you think i could get and what would be the best cable etc.
