Sure, glad you found it helpful! I found this technique on a youtube video as a way to install speakers in otherwise difficult locations simply by installing them into the (gutted) old/stock speakers. That said, even so there aren't many (I only really found one, which is the one I used) speakers that are shallow enough to fit. I recommend you give it a try, because it's very doable even for a first attempt at something like it. You just need some standard tools and you can probably do it in less than an hour even if you take your time. It's easier if you use the factory speaker wire of course also.
