Custom systems. Lets see what's out there

[Nester6662]

So I have this idea I want to try and add as many speakers in my truck without losing to much space. I'm talking everything mids, highs, down to sub enclosures. I'm interested in seeing what you guys out there have done, I'm sure I'm not the first to think of this and I'm sure I won't be the last. I seem some threads around with custom pods in the door etc but I'd like some more ideas plus I think it'll make a nice thread for everyone to show off ha
