I got some wal mart brand 'put together yourself' 6x9 boxes they do the speakers bass pretty well and look the same size box that any other store sells. I am guessing it probably isn't as sealed as other stores would sell them though, since it is a 'put it together yourself' box.
What type of sealer do I use?
Also having taken the speakers out a few times the screw holes aren't 100%, can I seal up the holes then drill into them again or will that not work? Or do I have to buy new boxes?
