Amp load affecting A/C?
I recently installed 2 amps (JL Slash 500/1 and 300/4) that were previously installed in my old '04 z06 into my '10 Grand Sport and all was fine for a day before I started to get some whine (I think it's due to the HU being grounded into the factory harness with the amps being grounded at the battery in the trunk). I'm hoping I can get rid of this whine by running a ground from the HU to the amps alongside the remote turn-on wire (which I ran right up the transmission tunnel).
Today, the whine is the worst that it has been since I installed everything 3 days ago, and I further noticed that my AC was not blowing cold when sitting at stop lights, unless I turned the HU off.
I assumed that the electrical load was too large so the car's computer was selectively choosing which accessories to turn on/off; is that a safe assumption?
It was my understanding that the factory alternator should be just fine with 2 amps of this size, am I mistaken?
Could the ground issue be the cause of this?
Thanks in advance!

Appears to be a coincidence in timing between the issue showing up and the amplifiers getting installed... The top plug to the fan control module appears to be scorched in the middle plug (the ground) which would cause the issue of the A/C condenser/compressor shutting off at idle (as it requires the fan to run at idle/low engine speeds) and the new issue detailed in post #3 of the car overheating when stationary.
Hopefully this post will help someone searching with similar symptoms in the future: check the wiring/plugs for the fan control module! Here are a few helpful threads/posts:
