The hardest thing about this unit was the subs because at first i didn't know what to do until i looked at it really closely and i finally got it.

The first thing i probobly didn't get was the subs and how they work but then i figured it out by looking at it closely

If i had to teach my parents something about the unit it would probobly be the clocks because there fun to work with and they are really easy to get used to
