i drove 20 minutes ish around the town right after i replaced the battery. and i parked. then today, i tried to start, didn't start.. so i jumped, then it started..
can you guys help me what is wrong with it?
If i replaced new battery and alternator, yet car won't start unless i jump the car.. what is wrong with it..?
You starter is probably shot and dragging. They get to where it takes more and more power to start. What is probably happening is it is pulling way too many amps. The new battery isn't even enough it needs a second battery to give it enough to turn.

Don't panic, it could still be the battery.
Often new batteries are really flat, and your 20 minutes may not have been enough to charge it up.
Go for a longer drive with higher revs, and you should be ok
How did you know you needed a new alt? You have a current draw somewhere. Check the trunk light or the glove box light. The switch may be bad.
If you have a good charge on the battery and this happens, but then, if you disconnect the battery cable overnight, replace it to find it starts, you have something drawing current when it shouldn't be.
