Sorry if this has been asked before, but I searched for a bit and didn't find what I was looking for. I have a '12 with the 130 and uconnect with 6 BA speakers and the 276 watt amp. I'm wanting to add the OEM trunk kicker speaker and box and need some help. I've read about the 276 and 368 amps having the same part numbers and having to reprogram to get the rear deck sub working. I would like to know what needs to be done to add the trunk speaker. For risk of sounding stupid, will I need to get the upgraded 368 watt amp in order to connect the wiring harness or to do it without having to tap into the rear speakers or will the 276 be enough to power it? Also, will the 130 need to be upgraded? Anything helps, thanks.
