The installation went great! It's funny you say that about doing something even tho I'm a rookie, because all of my friends kept telling me the same thing. To just bring it to a shop. But I've always been eager to try new things. Plus I've been working on cars, bikes, mowers, basically anything with a motor for most of my life. So I can typically figure things out once I have it in front of me.
With that said, I will say the hardest part was honestly taking the center console apart . I was more terrified I'd snap the plastic than I was anything else lol. But once everything was out, the stock head unit came out, I spliced the adapter into the stock radio wiring harness, ran the wiring/cables to the trunk and hooked the amp and subs up. I wish I took pictures while doing it(probably coulda made a decent write up for future fellow legacy owners, but unfortunately the thought never occurred to me while doing this project.
I will say I am very surprised at the subs performance. I definitely didn't think I'd get that much kick out of them, especially since I did stuck to a more "budget friendly" route. But no wires have come undone or anything, original fuse is still with the power wire. Only time I notice an "issue" is when it's freezing outside, the subs take a minute to warm up. And even that I'd say is normal, so really no complaints at all. Oh, except how little room you have when you take the head unit out. That and the radio harness isn't very long so splicing wires in that area was a bit of a challenge, but nothing too crazy. And the best part about all of this, I still have my steering wheel buttons, bluetooth, etc. (I know they make aftermarket harnesses so you can keep your steering wheel buttons, but that's more money lol)
