If you're happy, that's all that matters.
+2 to that.
If you want some opinions though. I personally don't like the black on tan. I have a gauge pod on the pillar that is black on top of the gray panel and I can't stand it. You should paint or cover the pods in the doors and the pillars to match. That or if you are changing the interior, get the rest of the stuff in black. Sometimes mixing colors turns out really well, but in the case of pods (from what I have seen) they just look out of place when they are different colors. It really just looks like they are stuck on top and don't blend in like they should.
The concept and idea was great. I really like door pods like that, but they should be flushed and blended in as to look like a part of the door not just mounted on top.
I also like the sub box. I just needs finished. The raw material isn't that appealing, but it isn't seen so I can understand where you are lax on that.
I like the flush panel you did over the amps. I am going to do that to mine when I get the chance. I really don't like that you can see all the wires on mine. They are just stuck in for now and I will come up with something a little nicer in the future.
All in all, great ideas, it just needs a little working, flushing, color matching, and finishing.
