Would a stock battery of a 2000 RX 300 be able to handle a 1000 watt amp without any problems

Simple answer is kinda. For more info I would suggest buying a deep cycle battery that is equal to the size of the stock battery. Or you can buy a 34 series battery which will fit but you will have to extend your factory connections because I don't think they make a 34 with the "R" which is reversed terminals like on our RX. If you truly want "no problems" then I recommend doing a Big 3 upgrade to your factory wiring also which is adding larger gauge wiring to existing wires to handle the extra load. Hope that helps..
