Okay now that you cut the hole in the box its time to put the speakers in! But before you put the speakers in you must bridge the two speakers together. Back to the cutting. Line the speakers up with the hole. Once they are lined up start putting the screws in. BUT BEFORE YOU PUT THE SCREWS IN PUCH LITTLE HOLES THROUGH THE BOX FROM THE BACK TO SEE WHERE TO PUT THE SCREWS IN. This should help. After you screw the screws in (from the front) take your hot glue gun and put glue over te screws. DO THIS IN THE BACK OF THE BOX! Then put a little glue around the edges of the back of the speaker. The glue will help the speaker stay attached to the box. After that you are done with the installation of the speakers.
