Brake Light, ABS Issues after aftermarket speakers and amplifiers installed -2014 JKU

Just a heads up...
I recently had a subwoofer/amp installed along with all the EOM speakers replaced and an additional amplifier installed to power them as well (while keeping the factory head unit - in my 2014 JKU

I picked up my Jeep from the installer and while driving away I noticed my brakes felt "funky", then I noticed my brake dash light was on, then I noticed a whiney/dull motor/fan type sound (with the stereo powered off).

I spent the better part of the day yesterday combing the web trying to find what the potential problem/resolution might be...

I found a plethora of potential problems - CAN-BUS corruption, brake light switch issues, grounding issues and more.

Here's what it was...
During the install, the younger shop newbie while drilling a hole through the firewall to run wire, came up a little high and put a hole on the bottom-backside of the brake booster.

Thankfully, they found it pretty quickly, they're paying to have it replaced etc. I just wanted to post this little FYI up on here in the event that someone someday runs into a similar issue.

I just bought my first Jeep 2 weeks ago, joined this forum soon after and have found it to be a great resource.
