to be honest, i really recommend you get a new head unit. Ask anyone you like, the difference in sound quality is reallly substantial.
you can run an amp off the renault headunit, you need to get an amp that accepts speaker input. so basically your using your speaker wire instead of an rca.
however rcas are far better!
but give it some thought, however id really recommend getting a new head unit, even a cheap £100 will sound much better...also look better
