Recently got a aftermarket head unit for my 07 GMC Canyon. During the installation I had to splice the ignition wire into another wire that had 12V during ignition. Decided to splice into a wire from the AC unit. This worked out and everything seemed fine until I tried using both the AC and head unit at the same time. The head unit shuts off completely when the AC is at a specific power but works fine when it is off. This was my first time ever doing electric work and don’t understand what is causing this or how I can fix it . Is there a possibility I can get it to work in its current set up, or am I best off just splicing into something else instead. Any help is appreciated.
