Hi all, new to the forums. Just got a 2018 GT, I'm really disappointed with the base radio performance compared to my last GT base radio. That said, I'm looking to install a small amp and want to access the back of the head unit. I can't figure out how to get it out, nor can I find any wiring diagrams. Any info would be appreciated. I may even post the upgrade to youtube since so little info is available. Thanks in advance.
