Hi guys, haven't posted in about 6 months, but yeah, i just wanted to share this with you.
I have started to build a fiberglass sub box for the back of a 2005 E53
to date i have only started constructed the form fitting piece that fits down into that little cavity, as you can see in the photo's its still paper thin, will hopefully finish this and the rest of the box in the next few months.
Cheers
Tom
