AMP+ Power supply questions

I have some questions regarding the power supply.
What is the difference with using a 12v or 18v supply?
For a lower voltage do I need a higher current?
Can I also use a 15v supply or does it has to be 12v or 18v?
I have some spare laptop powersupplies of 18.5v and 19v. If I would use them would I dammage the AMP?
