Kicker Hideaway Install - Back Speakers Aren't Working
 

I just got everything buttoned up for the install of my new Kicker Hideaway subwoofer. I tapped into the rear speaker wires for input and the subwoofer isn't working and the same goes for my rear speakers. I made sure all the connections are tight and everything was done correctly. Any ideas what the problem might be? There isn't a fuse for the speakers alone is there? Thanks in advance!
