I purchased a 2016 2575RCW with Kicker LED speakers. I can't find how to get speakers to light up. Looks like only the blue and black wire is hooked. I have been trying to find where all the LED speaker wires are connected. I have looked under the dash but can't find it. I have a Mood light switch and dimmer switch on the dash but it doesn't seem to control anything. Any help will be appreciated.
