I just replaced my rear speakers, and it was really very easy, due to a simply little tool I picked up a couple of months ago at Sears. I don't know what its called, but its a small round tool that will hold screwdriver and torx bits, and you turn it with your fingers. It remember it was only a couple of bucks. They had a bucket of them at the checkout, so I picked one up with my purchase, and then threw it in my tool box. I had forgotten about it until I went to get the torx bit for the speaker screws. That little thing made a huge difference in getting those screws out, especially the rear ones near the glass. It is small enough that you can get it back there on the screw, and still have enough window clearance. The whole job only took about :20 minutes. I attached a picture, along with the torx bit to show how small it is. BTW, I installed Infinity 6812s in the rear, and tomorrow I'll tackle the doors. I can already tell a big difference in sound quality, just from the rears........

 

Nice tip!!! Could have used this last month when I did my install

 

Indeed -- this might be worth a sticky IMHO.

 

Great tip, you can also use a 1/4" box end with the torx bit. I have a rachet wrench in 1/4" so it worked great.

 

I got one of those tools for Christmas and had no idea what it was for....thanks for the info!
