So i put my subs and amp into my 2010 civic, with its very easy to get to radio (sarcasm).. and everything worked out fine...until at night when i turned my subs on and lights on at the same time and got EXTREMELY heavy interference in the subs.. any ideas? Im thinking the wire we tapped into with the remote wire is somehow someway wired with the lights and thats where we are getting it...im not sure though... please help..thanks

 

Just a little side note. You don't have to wire the in/out converter to the head unit. You can do it in the trunk on the speakers considering they are the same exact wires.

Tap a different wire for your remote. If you have a 12v socket in your console then take the console out and tap the yellow wire. Don't tap random wires...
