MATCH PP AUDIO SET UP?

Hi, 

I've just bought the match pp 62dsp and match pp 10w-q - 10" subwoofer. Does anyone have a match audio fischer set up on their car. If so is it all plug and play or did you connect anything to the battery.

How does the car perform since the install if all totally plug and play, and any battery issues.

I have a 2015 VRS which has start/stop. This is all new to me the pug and play but I've been assured it all connects and works up fine. I'm just a tad anxious about power and battery.... If I need to connect to the battery then I'm very anxious about disconnecting it due to hearing how many issues that can potentially cause once it's been disconnected and reconnected. 

My dad used to work in the car industry fitting audio and alarms, and he is insistent on the amp and sub having to be connected to the battery, but has never worked on newer cars or ones that have this kind of technology.

Thanks
