Alright, I'll be the negative one today.
Being able to hook up and amp and being able to hook it up properly, are two different things. I highly recommend that you have someone with more car audio knowledge do the install. Preferably, someone that installs for a living.
I do my own installs, but I am 50 years old and have been installing car audio since the age of 15. I also apprenticed with a pro installer for a couple years while I was in the military. I worked at his shop and he gave me car audio as payment.
And there are still times that I research, research, research, before I do an install. I just did a head unit in a 2019 Nissan Frontier SV Crewcab. I spoke with Jerry Ferguson at Axxess for a couple days planning the install. When I was done, it was plug and play. No factory wires were cut, I just had to repin a 40 pin harness and the 20 pin harness.
So what am I saying? There is no shame in asking for help. Hell, ask the person if you can watch the install. Some installers don't mind being teachers.
