Punch small holes at the back of the tennis ball on each side with scissors or a stanley knife for the wire to go through

Soldering
Then correctly solder the wires to the right speakers. Making sure you do not burn the tennis ball.
Finishing Off
Carefully pull the wire through the tennis ball to bring the speaker into place. If you wanted you could glue the edge of tame of the speaker to the side of the tennis ball.
Velcro
Cut your velcro in half. One for each side of the tennis ball. Then on half of the velcro cut the furry side in half. As shown in the picture.
Then with the furry sides glue to the tennis ball where the two halfs meet. Look at picture if you need more help.
Do this on two section of the tennis ball one on the opposite side to the other.

Amp
Get your amp and find a suitable size box for it. For mine I used a treasury tag box.
Firstly mark out were you will need to put holes for the buttons and switches. Then carefully cut them make holes in the box with a pencil or something. Slide in the circuit board making sure that all buttons are carefully aligned. Glue the board to the box so the board does not slide about.

Battery
Slide the battery connected to the amp into the box. Do not glue this down because you will want to change the battery at some time. Make sure you have a small gap on one side of the box for the wires to go through.
Close up the box.
And try it.
