Should be simple question I can't get an answer for.
Have a 2015 GC with 8.4 rn, 6 speaker set up. I want to put a small powered sub in the back. Can I piggyback off one of the rear singles and wire power to the battery under the seat? Do I need a DSP of some sort? Will I loose any stock uconnect functionality? Any other suggestions to increase the bass of the 6 speaker without investing too much? Thanks in advance.
