Hello, I have a 2013 Chrysler Town and Country Touring edition. It has the 430 uconnect without navigation but has the bluetooth. I want to add an amp and subwoofer to it. Is there an adapter to add the L R plug ins that you would use to connect to the amplifier? I was trying to avoid upgrading the whole radio only because I just bought the van and want to just add the amp and subs from my old car. Thanks in advance everyone.
