Push the bolt through to the inside the the door,
Ah thanks. I've seen a few on eBay, always worth getting rid of stuff on there for a few quid, but I can imagine it is a bit of a hassle too for something almost worthless.
I don't quite get your clothes peg method - would a clothes peg even provide enough grip? Plus if they're on the inside, how do I get them out after the speaker is mounted and blocking the hole?
Opposite way from the way you done the front,
Could use blu-tak either,
Just to hold the bolt in place while you slide on the speaker,
Then secure down with one nut on each.
Head of bolt is inside the door pointing out at you
