Midrange Installation
My DLS 3" domes are going to go in kickpanels, pointed directly at each other. They are sealed back, so volume is not a problem.
There's only one problem with this in a M3 - the driver's kick houses the deadpedal, hood release lever, and the trunk release button - ouch. The passenger side is just a flat area.

Taking a look with them removed, there's not much to gain by cutting out the carpet - maybe 1/2":

Well, a little dremel action and the driver's side looks like this:

The curve matches the passenger side perfectly.
Now I have a nice flat area - a bit small though. It's too bad that the carpet is not flat from the factory where the dead pedal was - it has a bulge that won't lay flat - but it has enough give to it.
I grabbed some MDF and cut out a few flat parts to fit nicely. Then with some sparcers and a few rings, you have this:

Add some fleece and resin, and you get this:

I trimmed them up a bit, and here's what they look like in the car:


To attach the kicks to the car, I had to install some brackets first. Some 1/2" MDF and a few screws later and you get these:

And here they are installed:


Now all I have to do is throw in the mids.
