There is a huge amount of information on the forum regarding audio systems. For 1k most people are going to tell you it's going to be hard to put a system together. 1k should get you a HU and some speakers. But the whole shabang for 1k might be difficult. The rear speakers on the Z (non touring) are fake, but with the size of the Z 2 good front speakers sound great.
Others on the forum can really give you more information than I can.
Congrats on the car!
