rear deck speakers

What did you use to cut holes? I'm too scared to cut into mine!!

I used a 5" hole saw, easy as butter.  I used small black cutting boards from lowes on the back for support.  I will take a pic of the backside this weekend so you can see how they are mounted.  They sound great, and of course I just use those at the sandbar or when hanging out so that I dont have to blast the inside speakers just to hear some music.

I almost think one more speaker in the middle would look sharp - probably sound fuller as well. Nice job.
