That's a smart woody
As a music lover, after market system is a must. All you really need is two 10" or one 12" (also a new deck with MP3/ACC/Bluetooth and speakers). Believe me.

move what you bought into the new car. Standard size deck will fit most cars (sedan/coupe), and sub/amp will work in any car so what you need to worry about is the speaker sizes - the aftermarket speakers may not fit into the new car.
