Yes car audio installation isn't rocket science. Years ago one of my gf wanted a system for her new car so I somehow voluntered to do the install without knowing a thing about it (other than having done electronics forever). Turns out it was pretty easy and I started doing the odd one on the side until I was doing quite a few custom installs, fiberglass, etc. One of my philosophies of life is "if that idiot can do it I'm sure I can figure it out too". Works most of the time for me (although I haven't tried any open heart surgerys yet....)
That said I haven't been playing with much of that for the last 8 years or so and I'm thinking about getting some replacement stuff. I use to use a lot of MB Quart and JL Audio stuff - more interested in SQ than the SPL. What's a good price/performer (facts/emotional/fictional whatever
now adays?
