I have a 2010 Model 308 millennium. Help...

Hello friends, as I mentioned in the title, I have a 2010 Model 308 millenium. I want to have a sound system, I have a budget of 1000 TL, I am waiting for your suggestions. My main question is, I do not want to change the original tape of the car. After I connect this system, will I be able to get full efficiency from the system, would the tape affect the system badly?

I am glad too Ahmet
