I'm new here and was unable to find this information in an old post.
I just leased a vehicle with naviagation and I want to put my previously used system in the new leased vehicle. I definitly cannot remove the navi because I'll loose almost all functionality of the dash. Is there some way I can just connect a wire to my subs to tell the amp to turn on (like the P.conn) and have a knob to adjust the volume of the subs ? Any help is appreciated !! Thanks guys !
