No, no cutting at all. When I say a little tight I mean that the interior door panel doesn't completely seal back on. The clips around the lower quadrant where the speaker is aren't completely in. Don't get the wrong idea, it's nothing you can actually see and it's not loose or anything. But if you run your finger along the bottom edge of where the inner door panel meets you'll feel an 1/16" gap. The back of the speaker magnet touches as well.
When I first installed them I was completely freaked because I thought I was getting no midbass. Turned out it was just the tweeters overpowering the midbass drivers. Once I got a pair of phoenix gold L-pads wired into the tweeters I was able to attenuate them further than the -2db the included passive crossovers alowed for. The setup sounds excellent now. Deep midbass and crystal clear highs. I'm giving them 80 watts off an Alpine f540 and using the stock HU.
