HELP!!!!! I tried doing this earlier in the week but it was getting dark. Came back today and all I have is a huge bundle of grey foam that refuses to budge. It feels like it's double-taped on both sides and appears to wrap all the way around the inside beneath the HVAC. Enough pulling yielded a small chunk of foam, but nothing else. Doesn't feel like anything inside it either. What am I missing here? Is it directly in front on the top (of three) levels or is it off to th side somewhere or is it buried under the magical mystery foam? Btw, the razor sharp thing is an understatement. It looks like they honed it as a single-sided sword blade for some reason!
HELP HELP HELP! (the car is still apart now)
Btw, the Polk DB400's are dropping right in and fit nicely using the stock holes, even where the stock plates were. The blaujunk was completely melted on one side and cracked up on the other. Joy!
(Btw, the DB525's (5.1/4s) won't fit without serious cutting/rework and won't look right. I tried.

Hoping the rear DB650's drop right in.
