Just finished a little system in my daily driver Mini Cooper. System was cheap to build, but sounds pretty good!
I like to make build logs when I do major installs on my vehicles. If you like Mustangs, here is my 68 with a 2.3T:

Anyway, I'm going to keep track of my audio build here. The car is a 2009 MCSa.
The build might take a while, but I am starting with the hard stuff. First off, subwoofer boxes. As we all know, space is at a premium in these cars. I am re-using an amp I already own, and it is huge. There is no way it will fit anywhere except the trunk, which would leave almost no room for an in-floor sub. At first I thought I would be able to fit two 8" subs on one side of the trunk, but after measuring I was not happy with some of the compromises I would have to make. But, I already bought the subs, these Infinity's:
These have pretty good reviews online, and meet two of my main criterea: Perform in a small sealed box and able to handle a decent ammount of power. They will be getting about 300 watts RMS each. However, the motors on these are pretty big, and I want to save as much trunk space as possible.
Access panels removed. The drivers side is much better than the passengers as far as space.
I noticed that the factory wiring runs through here. I will be doing the same with my stereo wiring, but that makes corner boxes kind of tricky.
I decided on a fiberglass box on each side. The front face of the box will end at the factory jack access panel, which makes them very slim. I will have to use the space inside the side access panels not only for airspace, but for the magnets of the subs to slide into.
Here is one side foiled up:
Notice in the mass of tape in the right hand corner. I ran a tube behind there that goes from the access hole down to the trunk floor. My plan is that once I glass over it, it will create a void that I can use to run all my wiring and keep it hidden.
Trunk all foiled up:
This took a long time, but I wanted to make sure I didn't get any glass on the car or carpet.
Here is one side with two layers of glass.
I haven't made a fiberglass box in about 10 years, I forgot what a PITA it can be. Anyway, notice how I went into that passenger side cavity as far as possible. There will be just enough room for the sub magnet to slide in there, tucking them way in. You can also see the "channel" I have made for the wiring, I did this on both sides.
