Not speaking on behalf of empeg but...

1) yes you will need to get an amplifier... most normal car stereo's that you install have an amplifier built into them, however, the empeg does not... as a result of this you have two choices...
i) buy an amplifier - you connect the unit to the amp and the speakers to the amp
ii) connect the unit up to your existing head-unit (space may be a problem here, but you would use the amp in your existing unit

2) The actual size of the hard drive in the unit is up to you (there are several choices of HD size when you order, but getting to the point of your questio, the hard drives are rated to run up to 55 deg. C... this should be fine for most places in the world, and I believe that is the operating temperature of the drives, they may be able to take more heat if they aren't spinning, so if you think your car is hotter than 55 deg. when you get in it, turn on the a/c or drive around with the windows open for a while before turning the unit on.
